What happens when Republicans root for failure?

US gets no job growth in August

There's a viscious negative cycle within the business community and Republican voters' psyche that is spreading throughout the nation.  They want Obama to fail.  If the economy does well, he won't fail.

They highlight every negative in the economy, and in fact they help it stay that way.
This will continue as long as everyone is "depressed".  Once these negative forces feel they are missing out on a personal economic boom, they will change their stance.  But Republicans control so much of the financial media news that it is difficult for optimism to flourish.  That and the fact that people tend to believe the negative and cynical much faster than the opposite.

To add to that, Republicans are controlling and driving a counterproductive political debate for austerity.

Cutting government spending and talking about how Social Security won't be there for future generations saddles the economic confidence and seeps into behavior.

There's nothing fundamentally wrong with the U.S. economy like a natural disaster that prevents work, or social unrest that is blocking growth.  This is all political attacks from the Republicans.

So far, it's working.
