"The parallels between the story of the origin of the Great Depression and that of our Long Slump are strong. Back then we were moving from agriculture to manufacturing. Today we are moving from manufacturing to a service economy. The decline in manufacturing jobs has been dramatic—from about a third of the workforce 60 years ago to less than a tenth of it today. The pace has quickened markedly during the past decade. There are two reasons for the decline. One is greater productivity—the same dynamic that revolutionized agriculture and forced a majority of American farmers to look for work elsewhere. The other is globalization, which has sent millions of jobs overseas, to low-wage countries or those that have been investing more in infrastructure or technology. (As Greenwald has pointed out, most of the job loss in the 1990s was related to productivity increases, not to globalization.) Whatever the specific cause, the inevitable result is precisely the same as it was 80 years ago: a decline in income and jobs. The millions of jobless former factory workers once employed in cities such as Youngstown and Birmingham and Gary and Detroit are the modern-day equivalent of the Depression’s doomed farmers.
The consequences for consumer spending, and for the fundamental health of the economy—not to mention the appalling human cost—are obvious, though we were able to ignore them for a while. For a time, the bubbles in the housing and lending markets concealed the problem by creating artificial demand, which in turn created jobs in the financial sector and in construction and elsewhere. The bubble even made workers forget that their incomes were declining. They savored the possibility of wealth beyond their dreams, as the value of their houses soared and the value of their pensions, invested in the stock market, seemed to be doing likewise. But the jobs were temporary, fueled on vapor."
Excerpt from an excellent, and brief, article in January's Vanity Fair. I think it's fantastic and worth your time to read.
