As usual, what the government is saying it's doing with the tax money they confiscate from you is far from the whole story. Money taken and redistributed supposedly with a fixed purpose is diverted from it's mission to the pet projects of politicians with no direct or indirect benefit to the American economy. You, your children and their decedents will still have to pay the bill in any case.
