From the piece:
Almost a quarter of all jobs in America now pay wages below the poverty line for a family of four. The Bureau of Labor Statistics estimates 7 out of 10 growth occupations over the next decade will be low-wage — like serving customers at big-box retailers and fast-food chains.
At this rate, who’s going to buy all the goods and services America is capable of producing? We can’t return to the kind of debt-financed consumption that caused the bubble in the first place.
