The existing stimulus has yet to be completely spent and has done little good in turning on the engine of private job creation. It is political and the Democrats want to be able to say, see all the money we are spending to solve the problem. Even the EUropeans are beginning to see the light and these pin heads are wanting us to dig a deeper hole. If you want to spend money do it on a business and capital gains tax cuts.
It's obvious the goal of the left is not to stimulate private sector jobs but to build an infrastructure where the government is by far the largest employer beholden to the democrat party and where private jobs exist only to service its employees. To pay for it all one tax on top of another will be levied from VAT to you name it. It's a scheme that could have come right out of the Kremlin.
