One partial solution:
Move the income tax rate on earned income of more than $400,000 annually back to the 1964 rate of 91%.
We could then reinstate the Glass-Steagall Act of 1933 or similar legislation, which was replaced by the Gramm Act of 1999, which put the foxes in charge of the henhouse at great profit to those listed above, but destroyed the economy for most of us.
