Yale University's Robert Shiller quotes Thomas Jefferson from a letter written in 1820, where he said about the passions in the North and South about extending of slavery to the Missouri territory: "this momentous question, like a fire bell in the night, awakened and filled me with terror." He says there are serious consequences of letting longterm unemployment continue. He cites a proposal by Edmund Phelps, Nobel prize winner in economics from Columbia University, which would have the government give a subsidy of $4.50 an hour for the lowest paid workers, with declining amounts till they earn $15 an hour. This proposal would cost about $150 billion and be aimed at reducing income inequality and making these lower paid jobs attractive. Other proposals for reducing unemployment are to use work-sharing on a national basis with government help.
