A:It won't!
There is a terrific book on the Great Depression. It is called "The Forgotten Man ," by Amity Shlaes and it details the means by which FDR needlessly prolonged the first depression with all of his spending, taxing and artificially inflating wage rates. The parallels are kind of frightening especially because we have so many people on the dole now and we all have so much more debt now than the WWII generation did.
