His theory is that history repeats itself and that there has been no government that has been able to avoid deflation and hyperinflation in the situation we are in right now.

In the end, the government cronies will get the contracts and things will continue as they have.
Before the rise of Hitler, the hyperinflation which destroyed the middle class in Germany was preceded by deflation. History doesn't repeat itself but it sure does rhyme.
