And all of those people have been conditioned to accept their circumstances. Companies can pay whatever they want. They would pay $5.15 an hour if most applicants accepted that reality.
Wealth redistribution to the top 10% is at an all time high. The "middle class" just accept that fact.

In 1997 Bill Gates was the richest man in America with a net worth of $38 Billion. Warren Buffet was second at $23 Billion
In 2017 the top 10 richest Americans are have a net worth of over $40 Billion. The top 5 have a net worth of over $50 Billions
The top 20 richest Americans have a combined net worth of $916.6 Billion dollars
