Yup, It finally gets down to one fatal element, the WAGES!!!
Prosperity can't exist when workers are not evenhandedly compensated and wealth is not equitably distributed.
We should create a reasonable system that the workers' needs should take precedent over Wall Street's needs.
As the lines saying in the book "Greenspan's Fraud"(Batra & Macmillan, page 152):
A bubble economy is born when wages trail productivity for some time and result in ever-rising debt. Then profits grow faster than productivity gains, and share prices outpace GDP growth. However, a time comes when debt-growth slows down, and demand falls short of output, resulting in profit decline and a stock market crash. Thus, the very force that generates the stock market bubble seeds its crash."
