the trillion-dollar conglomerates that inhabit this new financial world are not free enterprises. They are rather wards of the state, extracting billions from the economy with a lot of pointless speculation in stocks, bonds, commodities and derivatives. They could never have survived, much less thrived, if their deposits had not been government-guaranteed and if they hadn’t been able to obtain virtually free money from the Fed’s discount window to cover their bad bets.The fourth destructive change has been the hollowing out of the larger American economy. Having lived beyond our means for decades by borrowing heavily from abroad, we have steadily sent jobs and production offshore. In the past decade, the number of high-value jobs in goods production and in service categories like trade, transportation, information technology and the professions has shrunk by 12 percent, to 68 million from 77 million. The only reason we have not experienced a severe reduction in nonfarm payrolls since 2000 is that there has been a gain in low-paying, often part-time positions in places like bars, hotels and nursing homes.It is not surprising, then, that during the last bubble from 2002 to 2006 the top 1 percent of Americans — paid mainly from the Wall Street casino — received two-thirds of the gain in national income, while the bottom 90 percent — mainly dependent on Main Street’s shrinking economy — got only 12 percent. This growing wealth gap is not the market’s fault. It’s the decaying fruit of bad economic policy.The day of national reckoning has arrived.
