taxes and health care

[CRedskinsRule]

After seeing what examples people have thrown out, I would say that the Interstate has to be the best example of what the federal government can and should do, which is facilitate trade and commerce between the individual states. Plus, and I don't know the figures, but I believe it is mainly funded from user taxes at this point, except where major projects(or pork) are needed.
Somebody said NASA, and in the 60's-70's that may have been true, because no one corporation needed to control space technologies, but now, private corporations should be given the freedom and ability to research and develop space tools. NASA wastes as much as it spends (and personally I don't feel like spending Billions of dollars so that Russian and French astronauts can study cell growth in orbit around us)
