Theneweconomymayormaynotmaterialize,butthereisnodoubtthatthenextsocietywillbewithusshortly.Inthedevelopedworld,andprobablyintheemergingcountriesaswell,thisnewsocietywillbeagooddealmoreimportantthantheneweconomy(ifany).Itwillbequitedifferentfromthesocietyofthelate20thcentury,andalsodifferentfromwhatmostpeopleexpect.Muchofitwillbeunprecedented.Andmostofitisalreadyhere,orisrapidlyemerging.

Inthedevelopedcountries,thedominantfactorinthenextsocietywillbesomethingtowhichmostpeopleareonlyjustbeginningtopayattention:therapidgrowthintheolderpopulationandtherapidshrinkingoftheyoungergeneration.Politicianseverywherestillpromisetosavetheexistingpensionsystem,butthey--andtheirconstituents--knowperfectlywellthatinanother25yearspeoplewillhavetokeepworkinguntiltheirmid-70s,healthpermitting.

10.TheHistoryofChineseAmericans

ChinesehavebeenintheUnitedStatesforalmosttwohundredyears.Infact,theChinesehadbusinessrelationswithHawaiipriortorelationswiththemainlandwhenHawaiiwasnotyetpartoftheUnitedStates.ButUnitedStatesinvestmentscontrolledthecapitalofHawaiiatthattime.In1788,ashipsailedfromGuangzhoutoHawaii.MostofthecrewmenwereChinese.TheywereconsideredthepioneersofHawaii.TheImmigrationCommissionreportedthatthefirstChinesearrivedintheUnitedStatesin1820,eightin1830andsevenhundredandeightyin1850.TheChinesepopulationgraduallyincreasedandreached64,199in1870.

FormanyyearsitwascommonintheUnitedStatestoassociateChineseAmericanswithrestaurantsandlaundries.PeopledidnotrealizethattheChinesehadbeendrivenintotheseoccupationsbytheprejudiceanddiscriminationthatfacedtheminthiscountry.

ThefirstChinesetoreachthemainlandUnitedStatescameduringtheCaliforniaGoldRushof1849.Likemostoftheotherpeoplethere,theyhadcometosearchforgold.Inthatlargelyunoccupiedland,themenstakedaclaimforthemselvesbyplacingmarkersintheground.However,eitherbecausetheChineseweresodifferentfromtheothersorbecausetheyworkedsopatientlythattheysometimessucceededinturningaseeminglyworthlessminingclaimintoaprofitableone,theybecamethescapegoatsoftheirenviouscompetitors.Theywereharassedinmanyways.Oftentheywerepreventedfromworkingtheirclaims;somelocalitiesevenpassedregulationsforbiddingthemtoownclaims.TheChinesethereforestartedtoseekoutotherwaysofearningaliving.Someofthembegantodothelaundryforthewhiteminers;otherssetupsmallrestaurants.(TherewerealmostnowomeninCaliforniainthosedays,andtheChinesefilledarealneedbydoingthis"woman'swork".)Somewenttoworkasfarmhandsorasfishermen.

Intheearly1860'smanymoreChinesearrivedinCalifornia.Thistimethemenwereimportedasworkcrewstoconstructthefirsttranscontinentalrailroad.Theyweresorelyneededbecausetheworkwassostrenuousanddangerous,anditwascarriedoninsucharemotepartofthecountrythattherailroadcompanycouldnotfindotherlaborersforthejob.Asinthecaseoftheirpredecessors,theseChinesewerealmostallmales;andlikethem,too,theyencounteredagreatdealofprejudice.Thehostilitygrewespeciallystrongaftertherailroadprojectwascomplete,andtheimportedlaborersreturnedtoCalitbrnia--thousandsofthem,alloutofwork.Becausethereweresomanymoreofthemthistime,theseChinesedrewevenmoreattentionthantheearliergroupdid.Theyweresoverydifferentineveryrespect:intheirphysicalappearance,includingalong"pigtail"atthebackoftheirotherwiseshavedheads;inthestrange,non-Westernclothestheywore;intheirspeech(fewhadlearnedEnglishsincetheyplannedtogobacktoChina);andintheirreligion.Theywerecontemptuouslycalled"heathenChinese"becausethereweremanysacredimagesintheirhousesofworship.
