What is a capitalist r private enterprise ecnmy? Firms are privately wned. Alternative is gvernment wnership. Cmmunism attempted central cntrl. Scialism tday refers t the welfare state.

Micrecnmics is the study f markets We assume yu have taken micr-ecnmics. Or read the review f micr suppliment. In private enterprise ecnmies, it is in the marketplace that three fundamental decisins are made: 1. What will be prduced? 2. Hw will it be prduced? 3. Wh will cnsume it? Adam Smith wrte in The Wealth f Natins: "It is nt frm the benevlence f the butcher, the brewer, r the baker that we expect ur dinner, but frm their regard t their wn interest." Market ecnmy harnesses self-interest fr benefit f sciety. Altruism is rare. True evil is rare t! 12 12

Is recvery pssible in 09? Are trade agreements like NAFTA gd? Or des free trade cst jbs? Entitlements are a majr issue: Scial Security & Medicare: transfer frm yung t ld, r insurance benefits that were paid fr? Can the birth dearth generatin affrd the "baby bmers " " benefits? Will they be willing t pay the tab? Is there any way ut f the mess? Is it actually a huge Pnzi scheme??!! Hw are entitlements affecting: Medical care? Educatin? Ecnmic grwth? The welfare f yung families? 14 14
Ecnmics and electins: Ecnmy is usually the # 1 issue Bill Clintn s s mantra in 92: It s s the ecnmy, stupid! Candidates prmise smething fr nthing, always mre than they can deliver. Ecnmy is best predictr f electin. Recessin means incumbents in truble! The End! 15 15
