Government can only consume, it does not "invest." What they do not want to tell you is that this money has to come from somewhere. Instead of letting the masses of people decide what to do with their own money (i.e. what types of goods to produce), politicians in Washington have determined that what you really want is roads and bridges. This is not job creation, but a reallocation of money from the private sector to overpaid employees in the public sector. It will actually reduce employment. Whereas the private sector will pay employes close to their marginal productivity, the government pays well in excess of the productivity of the individual. Thus, given the same pool of capital to pay employees, the private sector will hire more and produce more goods.
