Congress spends every penny now. There are increasing surpluses for them through 2009. Then the gravy starts to dry up. Disposable money starts to fall each year after having increased for many years. Congress will twitch and scream like stuck pigs.
The money will go into investments which inevitably will help grow the economy. This in turn will lead to greater greater government revnues over time. Any time the money is kept from the clutches of congress the country is better off!
The stock market has a record of going bust every now and then and a nation of people can not afford this.
