Government has succeeded in destroying so much of what was special about America. We used to often here "it's a free country" and people really meant it. We used to believe that the world was open to any who wished to apply themselves and they could expect equal treatment from a government designed to protect their right to life, liberty and the pursuit of happiness - a government whose sole function was to protect the freedom of the people, not to rule over us.
Yeah it wasn't perfect. Yeah it didn't cover some people well if at all for a long time. But it was based on something radically different than almost any government before. And that difference made a huge difference in the economic realm as well when freedom extended as free trade - voluntary marketplace interactions only.
Bit by bit the people have forgotten freedom. Bit by bit those with a very different vision whether the State rules the people and a person is subservient to the state has taken over. And it has hurt economically as well. There are over 400,000 regulations on the books. The amount of red tape on business is ridiculous. The amount of limiting of choice of what can be offered for sale or purchased is extreme and growing. The State eats 40% of wealth and more as it has us $19 trillion in debt and at least $100 trillion more in hock for unfunded liabilities.
So don't pretend that the rich did it or some unknown malady has befallen us. Look to government and to the people forgetting freedom and what this country is supposed to be about.
