Just shut the SnP out of business.. we don't need them. it is easiest and most feasible solution probably. Seriously, I don't understand this stuff but I'm think SnP may have overreached. For one, if markets discount the downgrade which is likely in the intermediate to long term then SnP own credibility will be lower. Short term it will create for volatile markets and maybe some once in a lifetime buying opportunities of stocks.
The credit rating will continue to be downgraded further so long as spending remains out of control and we keep printing money excessively.
Shut down 80% of the banking/finance industry. Throw out the guest workers (H1-B's) and cancel the green cards of anyone who got one in the past decade. Get all the engineers back to work creating things. Probably have to sit down with the Canadians and come up with a North America energy policy. An immediate 'crash program' in energy conservation very likely will be required.
