I think we are getting very little for our 10 billion and I don't think giving them more money will get us more space. As for the military budget, I do believe we spend too much there, but taking that money and having NASA waste it instead doesn't feel like that much of an improvement.
As for the 1997 figure, I guess the .5% argument would be useful for the people so horribly uninformed, and you are right that this probably explains why I keep hearing this argument. Fair point.
