I read that Mother Jones editorial write-up in connection with another thread.
Fact is used to come to a laughable conclusion.
The rich nearly all are productive entrepreneurs, making jobs for those of us who make up the middle and 'working' classes.
Steve Jobs, Koch brothers, Walmart owners, etc., etc.

The labor market is undergoing change that has temporary downsides.
Workrs are being replaced by automation, the growth of cheaper labor sources in countries like China and India, and the unstoppable globalization as peoples come closer to common ground.

Japan has high wages so has lost the mass goods market, but strong education policies and entrepreneurship has helped, but as China, etc., follow the same path of higher wages and strong education, Japan is showing signs of slowing down.

No real answer; we are in a post-industrial period and problems will be many until the new methods take over. I am afraid that our surplus populations are in for harder times.

Mother Jones and that ilk offer no solutions, only complaints.
