This crisis hasn't proven anything relevant to this post. This crisis has revealed that the major world banks have been insolvent since the mid 80's, but have been propped up by ponzi finance. Then, inflation got out of control and the world central banks thought they could reign it in without popping the bubble, since they have done it for about 30 years successfully. But, this time, the 600 trillion derivatives market collapsed. The US government may not be able to absorb the losses that it will take to revive the banking system, unless the whole world intervenes. What we have learned is that banks cannot chase profits at the expense of the real economy for long without causing a catastrophic failure.
