Could unemployment go to15%?

Will Obama/Pelosi policies drive unemployment to 15%?Detroit Mi.is already at 20%. America has one of the highest corporate tax rates in the world. Why would corps remain here when Canada and Ireland and other nations have considerably lower tax rates? Also corporate bashing is not good for jobs. The Dens don't seem to understand that they are setting in motion long term double digit unemployment with extreme taxation and deficits.
