I think for "main street", it will be a disaster. The fallout could rival the 1930's depression and people's 401Ks will probably loose 30% to 40% of their value.
Why Wall Street is still backing these GOP idiots is beyond me. We seem to be in a shift of US Party priorities. Seems the Dems are heading to support businesses while pushing social conscience. Seems some in the GOP is trying to do what they can to steal from Social Security/Medicare and crash world economy.
