The New Deal effective tax rates on individuals and corporations plus subsidies for public college created the greatest middle class in history. It also barred banks from loaning Wall Street money for speculative and risky adventures.
In 1980 Reagan began unraveling all of the pillars of that middle class success.
46 years later you can see the damage. Housing is unaffordable even for professional couples. Public colleges are gated to the upper classes.
There is no middle class anymore.
