Remember when George Bush was criticized by the mainstream media for "talking down the economy" during and right after his first run for the Presidency? Those comments pale to Biden's and Obama's. See here & here. Hmmm . . . where's the media now?
Note that Biden's "significant investment" and scare tactics are meant to soften up the opposition for the coming tax increases and massive government spending. Obama's comment that economic recovery "will take years" is meant to lower expectations to his impossible campaign promises and to deflect criticism when things do in fact get worse; which will happen in large measure due to more government regulations, taxes, and FDR type public works programs. It's going to be a wild ride.
