What should be done is arrest the major bankers right across the world for having perpetrated a giant pyramid scheme, try them all for fraud, and declare the existing government debts to the banks NULL AND VOID...cancel them...and start all over again at zero, with no national debt. There would then be plenty enough money in government coffers from the existing tax base to provide all our social services and maintain our public infrastructure.
Then nationalize all the stuff that's been privatized and sold off to private industry in the past 40 years of neocon robbery/insanity.
And nationalize the damn banks too.
Start doing things to help the general public across this world instead of just to make obscene profits for a tiny consortium of billionaires.
