Take the winds out of the financial sails

I am not a banker, and they will probably call this fanciful, but I do think we need to take the wind out of bank's sails, and make them subservient to national sovereignty, and better protector of OUR money. So,

Let's cap the interest on sovereign debt, to 4% say for everyone in the EU, and extend it all to 20 years. This means some will pay more (UK, Germany, France…) and some will pay less. Let the central banks smooth that out by issuing money to stop bank failures and by them seeking productive investments, let governments handle it by sweeping tax cuts so people spend.

In addition force fiscal inion of ALL 27 countries, including UK. Restructure the EU, yes I mean the EU, not the euro zone. Integrate more the politics and political decision making, let this control major fiscal policy, allowing freedom for local financing or taxes. But keep the banks small and local to prevent the "too big to fail" problem.

Stop the gambling and interbank shilly shallying. Allow CDS only to first level, but insist backed by secure assets, like gold.
