　　Thegroundexpensesofthelandlord，however，togetherwiththeoriginalandtheannualexpensesofthefarmer，aretheonlythreesortsofexpenseswhichinthissystemareconsideredasproductive。Allotherexpensesandallotherordersofpeople，eventhosewhointhecommonapprehensionsofmenareregardedasthemostproductive，areinthisaccountofthingsrepresentedasaltogetherbarrenandunproductive。
　　Artificersandmanufacturersinparticular，whoseindustry，inthecommonapprehensionsofmen，increasessomuchthevalueoftherudeproduceofland，areinthissystemrepresentedasaclassofpeoplealtogetherbarrenandunproductive。Theirlabour，itissaid，replacesonlythestockwhichemploysthem，togetherwithitsordinaryprofits。Thatstockconsistsinthematerials，tools，andwagesadvancedtothembytheiremployer;andisthefunddestinedfortheiremploymentandmaintenance。Itsprofitsarethefunddestinedforthemaintenanceoftheiremployer。

　　Artificers，manufacturers，andmerchantscanaugmenttherevenueandwealthoftheirsocietybyparsimonyonly;or，asitinthissystem，byprivation，thatis，bydeprivingthemselvesapartofthefundsdestinedfortheirownsubsistence。Theyannuallyreproducenothingbutthosefunds。Unless，therefore，theyannuallysavesomepartofthem，unlesstheyannuallydeprivethemselvesoftheenjoymentofsomepartofthem，therevenueandwealthoftheirsocietycanneverbeinthesmallestdegreeaugmentedbymeansoftheirindustry。Farmersandcountrylabourers，onthecontrary，mayenjoycompletelythewholefundsdestinedfortheirownsubsistence，andyetaugmentatthesametimetherevenueandwealthoftheirsociety。Overandabovewhatisdestinedfortheirownsubsistence，theirindustryannuallyaffordsanetproduce，ofwhichtheaugmentationnecessarilyaugmentstherevenueandwealthoftheirsociety。Nationsthereforewhich，likeFranceorEngland，consistinagreatmeasureofproprietorsandcultivatorscanbeenrichedbyindustryandenjoyment。Nations，onthecontrary，which，likeHollandandHamburg，arecomposedchieflyofmerchants，artificers，andmanufacturerscangrowrichonlythroughparsimonyandprivation。Astheinterestofnationssodifferentlycircumstancedisverydifferent，soislikewisethecommoncharacterofthepeople:inthoseoftheformerkind，liberality，franknessandgoodfellowshipnaturallymakeapartofthatcommoncharacter:inthelatter，narrowness，meanness，andaselfishdisposition，aversetoallsocialpleasureandenjoyment。
　　Theunproductiveclass，thatofmerchants，artificers，andmanufacturers，ismaintainedandemployedaltogetherattheexpenseofthetwootherclasses，ofthatofproprietors，andofthatofcultivators。Theyfurnishitbothwiththematerialsofitsworkandwiththefundofitssubsistence，withthecornandcattlewhichitconsumeswhileitisemployedaboutthatwork。
　　Theproprietorsandcultivatorsfinallypayboththewagesofalltheworkmenoftheunproductiveclass，andoftheprofitsofalltheiremployers。Thoseworkmenandtheiremployersareproperlytheservantsoftheproprietorsandcultivators。Theyareonlyservantswhoworkwithoutdoors，asmenialservantsworkwithin。
　　Boththeoneandtheother，however，areequallymaintainedattheexpenseofthesamemasters。Thelabourofbothisequallyunproductive。Itaddsnothingtothevalueofthesumtotaloftherudeproduceoftheland。Insteadofincreasingthevalueofthatsumtotal，itisachargeandexpensewhichmustbepaidoutofit。
　　Theunproductiveclass，however，isnotonlyuseful，butgreatlyusefultotheothertwoclasses。Bymeansoftheindustryofmerchants，artificers，andmanufacturers，theproprietorsandcultivatorscanpurchaseboththeforeigngoodsandthemanufacturedproduceoftheirowncountrywhichtheyhaveoccasionforwiththeproduceofamuchsmallerquantityoftheirownlabourthanwhattheywouldbeobligedtoemployiftheyweretoattempt，inanawkwardandunskilfulmanner，eithertoimporttheoneortomaketheotherfortheirownuse。Bymeansoftheunproductiveclass，thecultivatorsaredeliveredfrommanycareswhichwouldotherwisedistracttheirattentionfromthecultivationofland。Thesuperiorityofproduce，which，inconsequenceofthisundividedattention，theyareenabledtoraise，isfullysufficienttopaythewholeexpensewhichthemaintenanceandemploymentoftheunproductiveclasscostseithertheproprietorsorthemselves。Theindustryofmerchants，artificers，andmanufacturers，thoughinitsownnaturealtogetherunproductive，yetcontributesinthismannerindirectlytoincreasetheproduceoftheland。Itincreasestheproductivepowersofproductivelabourbyleavingitatlibertytoconfineitselftoitsproperemployment，thecultivationofland;andtheploughgoesfrequentlytheeasierandthebetterbymeansofthelabourofthemanwhosebusinessismostremotefromtheplough。

　　Themerchants，artificers，andmanufacturersofthosemercantilestateswhich，likeHollandandHamburg，consistchieflyofthisunproductiveclass，areinthesamemannermaintainedandemployedaltogetherattheexpenseoftheproprietorsandcultivatorsofland。Theonlydifferenceis，thatthoseproprietorsandcultivatorsare，thegreaterpartofthem，placedatamostinconvenientdistancefromthemerchants，artificers，andmanufacturerswhomtheysupplywiththematerialsoftheirworkandthefundoftheirsubsistences—theinhabitantsofothercountriesandthesubjectsofothergovernments。
　　Suchmercantilestates，however，arenotonlyuseful，butgreatlyusefultotheinhabitantsofthoseothercountries。Theyfillup，insomemeasure，averyimportantvoid，andsupplytheplaceofthemerchants，artificers，andmanufacturerswhomtheinhabitantsofthosecountriesoughttofindathome，butwhom，fromsomedefectintheirpolicy，theydonotfindathome。

　　Thiscontinualincreasebothoftherudeandmanufacturedproduceofthoselandednationswouldinduetimecreateagreatercapitalthancould，withtheordinaryrateofprofit，beemployedeitherinagricultureorinmanufactures。Thesurplusofthiscapitalwouldnaturallyturnitselftoforeigntrade，andbeemployedinexportingtoforeigncountriessuchpartsoftherudeandmanufacturedproduceofitsowncountryasexceededthedemandofthehomemarket。Intheexportationoftheproduceoftheirowncountry，themerchantsofalandednationwouldhaveanadvantageofthesamekindoverthoseofmercantilenationswhichitsartificersandmanufacturershadovertheartificersandmanufacturersofsuchnations;theadvantageoffindingathomethatcargoandthosestoresandprovisionswhichtheotherswereobligedtoseekforatadistance。Withinferiorartandskillinnavigation，therefore，theywouldbeabletosellthatcargoascheapinforeignmarketsasthemerchantsofsuchmercantilenations;andwithequalartandskilltheywouldbeabletosellitcheaper。Theywouldsoon，therefore，rivalthosemercantilenationsinthisbranchofforeigntrade，andinduetimewouldjostlethemoutofitaltogether。

　　Whenalandednation，onthecontrary，oppresseseitherbyhighdutiesorbyprohibitionsthetradeofforeignnations，itnecessarilyhurtsitsowninterestintwodifferentways。First，byraisingthepriceofallforeigngoodsandofallsortsofmanufactures，itnecessarilysinkstherealvalueofthesurplusproduceofitsownland，withwhich，or，whatcomestothesamething，withthepriceofwhichitpurchasesthoseforeigngoodsandmanufactures。Secondly，bygivingasortofmonopolyofthehomemarkettoitsownmerchants，artificers，andmanufacturers，itraisestherateofmercantileandmanufacturingprofitinproportiontothatofagriculturalprofit，andconsequentlyeitherdrawsfromagricultureapartofthecapitalwhichhadbeforebeenemployedinit，orhindersfromgoingtoitapartofwhatwouldotherwisehavegonetoit。Thispolicy，therefore，discouragesagricultureintwodifferentways;first，bysinkingtherealvalueofitsproduce，andtherebyloweringtherateofitsprofit;and，secondly，byraisingtherateofprofitinallotheremployments。Agricultureisrenderedlessadvantageous，andtradeandmanufacturesmoreadvantageousthantheyotherwisewouldbe;andeverymanistemptedbyhisowninteresttoturn，asmuchashecan，bothhiscapitalandhisindustryfromtheformertothelatteremployments。

　　Thecapitalerrorofthissystem，however，seemstolieinitsrepresentingtheclassofartificers，manufacturers，andmerchantsasaltogetherbarrenandunproductive。Thefollowingobservationsmayservetoshowtheimproprietyofthisrepresentation。
　　First，thisclass，itisacknowledged，reproducesannuallythevalueofitsownannualconsumption，andcontinues，atleast，theexistenceofthestockorcapitalwhichmaintainsandemploysit。Butuponthisaccountalonethedenominationofbarrenorunproductiveshouldseemtobeveryimproperlyappliedtoit。Weshouldnotcallamarriagebarrenorunproductivethoughitproducedonlyasonandadaughter，toreplacethefatherandmother，andthoughitdidnotincreasethenumberofthehumanspecies，butonlycontinueditasitwasbefore。Farmersandcountrylabourers，indeed，overandabovethestockwhichmaintainsandemploysthem，reproduceannuallyanetproduce，afreerenttothelandlord。Asamarriagewhichaffordsthreechildreniscertainlymoreproductivethanonewhichaffordsonlytwo;sothelabouroffarmersandcountrylabourersiscertainlymoreproductivethanthatofmerchants，artificers，andmanufacturers。Thesuperiorproduceoftheoneclass，however，doesnotrendertheotherbarrenorunproductive。
　　Secondly，itseems，uponthisaccount，altogetherimpropertoconsiderartificers，manufacturers，andmerchantsinthesamelightasmenialservants。Thelabourofmenialservantsdoesnotcontinuetheexistenceofthefundwhichmaintainsandemploysthem。Theirmaintenanceandemploymentisaltogetherattheexpenseoftheirmasters，andtheworkwhichtheyperformisnotofanaturetorepaythatexpense。Thatworkconsistsinserviceswhichperishgenerallyintheveryinstantoftheirperformance，anddoesnotfixorrealizeitselfinanyvendiblecommoditywhichcanreplacethevalueoftheirwagesandmaintenance。Thelabour，onthecontrary，ofartificers，manufacturers，andmerchantsnaturallydoesfixandrealizeitselfinsomesuchvendiblecommodity。Itisuponthisaccountthat，inthechapterinwhichItreatofproductiveandunproductivelabour，Ihaveclassedartificers，manufacturers，andmerchantsamongtheproductivelabourers，andmenialservantsamongthebarrenorunproductive。
　　Thirdly，itseemsuponeverysuppositionimpropertosaythatthelabourofartificers，manufacturers，andmerchantsdoesnotincreasetherealrevenueofthesociety。Thoughweshouldsuppose，forexample，asitseemstobesupposedinthissystem，thatthevalueofthedaily，monthly，andyearlyconsumptionofthisclasswasexactlyequaltothatofitsdaily，monthly，andyearlyproduction，yetitwouldnotfromthencefollowthatitslabouraddednothingtotherealrevenue，totherealvalueoftheannualproduceofthelandandlabourofthesociety。Anartificer，forexample，who，inthefirstsixmonthsafterharvest，executestenpounds’worthofwork，thoughheshouldinthesametimeconsumetenpounds’worthofcornandothernecessaries，yetreallyaddsthevalueoftenpoundstotheannualproduceofthelandandlabourofthesociety。Whilehehasbeenconsumingahalf—yearlyrevenueoftenpounds’worthofcornandothernecessaries，hehasproducedanequalvalueofworkcapableofpurchasing，eithertohimselforsomeotherperson，anequalhalf—yearlyrevenue。Thevalue，therefore，ofwhathasbeenconsumedandproducedduringthesesixmonthsisequal，nottoten，buttotwentypounds。Itispossible，indeed，thatnomorethantenpounds’worthofthisvaluemayeverhaveexistedatanyonemomentoftime。Butifthetenpounds’worthofcornandothernecessaties，whichwereconsumedbytheartificer，hadbeenconsumedbyasoldierorbyamenialservant，thevalueofthatpartoftheannualproducewhichexistedattheendofthesixmonthswouldhavebeentenpoundslessthanitactuallyisinconsequenceofthelabouroftheartificer。Thoughthevalueofwhattheartificerproduces，therefore，shouldnotatanyonemomentoftimebesupposedgreaterthanthevalueheconsumes，yetateverymomentoftimetheactuallyexistingvalueofgoodsinthemarketis，inconsequenceofwhatheproduces，greaterthanitotherwisewouldbe。
　　Whenthepatronsofthissystemassertthattheconsumptionofartificers，manufacturers，andmerchantsisequaltothevalueofwhattheyproduce，theyprobablymeannomorethanthattheirrevenue，orthefunddestinedfortheirconsumption，isequaltoit。Butiftheyhadexpressedthemselvesmoreaccurately，andonlyassertedthattherevenueofthisclasswasequaltothevalueofwhattheyproduced，itmightreadilyhaveoccurredtothereaderthatwhatwouldnaturallybesavedoutofthisrevenuemustnecessarilyincreasemoreorlesstherealwealthofthesociety。Inorder，therefore，tomakeoutsomethinglikeanargument，itwasnecessarythattheyshouldexpressthemselvesastheyhavedone;andthisargument，evensupposingthingsactuallywereasitseemstopresumethemtobe，turnsouttobeaveryinconclusiveone。
　　Fourthly，farmersandcountrylabourerscannomoreaugment，withoutparsimony，therealrevenue，theannualproduceofthelandandlabouroftheirsociety，thanartificers，manufacturers，andmerchants。Theannualproduceofthelandandlabourofanysocietycanbeaugmentedonlyintwoways;either，first，bysomeimprovementintheproductivepowersoftheusefullabouractuallymaintainedwithinit;or，secondly，bysomeincreaseinthequantityofthatlabour。
　　Theimprovementintheproductivepowersofusefullabourdepend，first，upontheimprovementintheabilityoftheworkman;and，secondly，uponthatofthemachinerywithwhichheworks。Butthelabourofartificersandmanufacturers，asitiscapableofbeingmoresubdivided，andthelabourofeachworkmanreducedtoagreatersimplicityofoperationthanthatoffarmersandcountrylabourers，soitislikewisecapableofboththesesortsofimprovementsinamuchhigherdegree。Inthisrespect，therefore，theclassofcultivatorscanhavenosortofadvantageoverthatofartificersandmanufacturers。
　　Theincreaseinthequantityofusefullabouractuallyemployedwithinanysocietymustdependaltogetherupontheincreaseofthecapitalwhichemploysit;andtheincreaseofthatcapitalagainmustbeexactlyequaltotheamountofthesavingsfromtherevenue，eitheroftheparticularpersonswhomanageanddirecttheemploymentofthatcapital，orofsomeotherpersonswholendittothem。Ifmerchants，artificers，andmanufacturersare，asthissystemseemstosuppose，naturallymoreinclinedtoparsimonyandsavingthanproprietorsandcultivators，theyare，sofar，morelikelytoaugmentthequantityofusefullabouremployedwithintheirsociety，andconsequentlytoincreaseitsrealrevenue，theannualproduceofitslandandlabour。
　　Fifthlyandlastly，thoughtherevenueoftheinhabitantsofeverycountrywassupposedtoconsistaltogether，asthissystemseemstosuppose，inthequantityofsubsistencewhichtheirindustrycouldprocuretothem;yet，evenuponthissupposition，therevenueofatradingandmanufacturingcountrymust，otherthingsbeingequal，alwaysbemuchgreaterthanthatofonewithouttradeormanufactures。Bymeansoftradeandmanufactures，agreaterquantityofsubsistencecanbeannuallyimportedintoaparticularcountrythanwhatitsownlands，intheactualstateoftheircultivation，couldafford。Theinhabitantsofatown，thoughtheyfrequentlypossessnolandsoftheirown，yetdrawtothemselvesbytheirindustrysuchaquantityoftherudeproduceofthelandsofotherpeopleassuppliesthem，notonlywiththematerialsoftheirwork，butwiththefundoftheirsubsistence。Whatatownalwaysiswithregardtothecountryinitsneighbourhood，oneindependentstateorcountrymayfrequentlybewithregardtootherindependentstatesorcountries。ItisthusthatHollanddrawsagreatpartofitssubsistencefromothercountries;livecattlefromHolsteinandJutland，andcornfromalmostallthedifferentcountriesofEurope。Asmallquantityofmanufacturedproducepurchasesagreatquantityofrudeproduce。Atradingandmanufacturingcountry，therefore，naturallypurchaseswithasmallpartofitsmanufacturedproduceagreatpartoftherudeproduceofothercountries;while，onthecontrary，acountrywithouttradeandmanufacturesisgenerallyobligedtopurchase，attheexpenseofagreatpartofitsrudeproduce，averysmallpartofthemanufacturedproduceofothercountries。Theoneexportswhatcansubsistandaccommodatebutaveryfew，andimportsthesubsistenceandaccommodationofagreatnumber。Theotherexportstheaccommodationandsubsistenceofagreatnumber，andimportsthatofaveryfewonly。Theinhabitantsoftheonemustalwaysenjoyamuchgreaterquantityofsubsistencethanwhattheirownlands，intheactualstateoftheircultivation，couldafford。Theinhabitantsoftheothermustalwaysenjoyamuchsmallerquantity。
　　Thissystem，however，withallitsimperfectionsis，perhaps，thenearestapproximationtothetruththathasyetbeenpublisheduponthesubjectofpoliticaleconomy，andisuponthataccountwellworththeconsiderationofeverymanwhowishestoexaminewithattentiontheprinciplesofthatveryimportantscience。Thoughinrepresentingthelabourwhichisemployeduponlandastheonlyproductivelabour，thenotionswhichitinculcatesareperhapstoonarrowandconfined;yetinrepresentingthewealthofnationsasconsisting，notintheunconsumablerichesofmoney，butintheconsumablegoodsannuallyreproducedbythelabourofthesociety，andinrepresentingperfectlibertyastheonlyeffectualexpedientforrenderingthisannualreproductionthegreatestpossible，itsdoctrineseemstobeineveryrespectasjustasitisgenerousandliberal。Itsfollowersareverynumerous;andasmenarefondofparadoxes，andofappearingtounderstandwhatsurpassesthecomprehensionofordinarypeople，theparadoxwhichitmaintains，concerningtheunproductivenatureofmanufacturinglabour，hasnotperhapscontributedalittletoincreasethenumberofitsadmirers。Theyhaveforsomeyearspastmadeaprettyconsiderablesect，distinguishedintheFrenchrepublicoflettersbythenameofTheEconomists。Theirworkshavecertainlybeenofsomeservicetotheircountry;notonlybybringingintogeneraldiscussionmanysubjectswhichhadneverbeenwellexaminedbefore，butbyinfluencinginsomemeasurethepublicadministrationinfavourofagriculture。Ithasbeeninconsequenceoftheirrepresentations，accordingly，thattheagricultureofFrancehasbeendeliveredfromseveraloftheoppressionswhichitbeforelabouredunder。
