Rising disability claims may explain America’s shrinking labour force … IN THE early 1980s the distressing persistence of high unemployment in Europe was labelled “Eurosclerosis”. Some now wonder whether “Amerisclerosis” is the right word to describe America’s labour market. It is true that unemployment has slowly dropped from a peak of 10% in late 2009, to 7.3% at present. But this decline overstates the health of the jobs market. … The labour-force participation rate, the share of the working-age population either working or looking for work, has plunged from 66% in 2007 to 63.2% in August, a 35-year low. If those people who have simply dropped out of the labour force were classified as unemployed, the headline jobless rate would be much higher.
