It is proven time and time again that gov't control in a free market society is detramental. The gov't agency's do not have the speed or the innovative drive to reform, and there lies the bases of the problem. No matter how the American banks played there game, mainly greed, but I believe they should have suffered for there greed, and not to be bail out, simple. Because in a free market economy there always lies another entrepreneur waiting to take the old banks place.
It is also proven time and time again that free economy without regulation lead to a dead end monopoly and revolution.
This is why in developed countries healthy regulations are always in place and being effectively executed. This financial crisis is precisely caused by lack of regulation and/or execution of the rules.
As most of major Chinese Banks are (at least partially) in public, it invites some external constraints. It can be good, but it can also be bad.
Improvement of banking system doesnt necessarily to be taken over by outsiders; it can also be achieved through government interferences as the US is currently doing.
