The evidence of past expansions of government programs is just the opposite. Once created they tend to survive and grow over time, even when the increases initially were said to be temporary. The underlying reason for this is that interest groups develop around new and expanded programs, and they lobby to keep and expand those programs.
Whatever the merits of other government spending, the spending in this package is likely to have less value. A very large amount of money will be spent quickly over a two-year period: $500 billion amounts to about one-quarter of the total federal government annual spending of $2 trillion. It is extremely difficult for any group, private as well as public, to spend such a large sum wisely in a short period of time.
I can't agree more, and so find this all so depressing. But I don't blame Obama or Democrats per se, as they are giving the US what it wants. I just think what most people want is not in their best interest, like voting for rent controls.
