System Correction:
Sure you can try to go in and fix a system, but a lot of people disagree with how you are going to do it. Central planning doesn't work due to information problems (lack of prices), and freedom issues. So any change you make to the system will be short lived, but then open up a can of worms as people are free to take risks and not worry about the downside. Second, a lot of people object to forcing people to do things at the point of a gun.
Productivity & Wage Increase
I think you are missing a fundamental point, when productivity increases it is normally the result of a capital investment. The person who makes that investment is the one who profits, not normally the person whose productivity has increased. For instance if I'm making shoes, and my boss buys a machine that allows me to increase my productivity 10 fold, well he will see most of that reward while I may see a small increase in my wages. He took the risk of investing in that machine, and thus should see the reward.

As for you last post I don't know if that is true or not, how much actual money have the banks lost -- not lost for their clients, but lost themselves.
