How do you see this happening, as I see things going exactly in the opposite direction? After every "financial crisis" the regulations and restrictions on banks increase. Governments and financial institutions are becoming more intertwined, not less. We are moving away from a "free market" system, not towards it.
It's true (and par for the course) that, after a financial bust, the elites have incentives to keep what remains of the bubble going by using regulation, capital controls, bailouts, etc. (E.g. before the euro, Italian savers were forced to stay in the lira which everyone knew was always going down.)
But I was talking about the long term. Imperial and other financial bubbles and busts have occurred for about 500 years in the West. They are not going away overnight. Only when the public wakes up to the core problem, which is quite simple when phrased properly, will they endorse the right solution, which is also simple.
The key is to come face to face with the very essence of the problem: the over-reach of the state into the monetary and financial markets.
