well, look. I'm an American taxpayer--or I would be, if I made any money*--and I really want manned spaceflight. I disagree that it's just to say we've been; I think humans can accomplish more in space, and I believe those accomplishments are important.
further, I know an awful lot of other American taxpayers, most of which would rather have a space program than (fill in name of government program here). yes, we'd rather have relief efforts to disaster-stricken areas, New Orleans just being a prominent recent example and far from the only one ever. however, just to throw out an example, I'd rather have a manned space program than a war--and the manned space program only takes a fraction of the war's budget. it also provides a lot of jobs, which in turn provides more money for the economy--which provides more taxes to pay for relief efforts and wars.
*well, technically, I do pay taxes--I pay sales tax to Thurston County. however, I doubt any of that goes to NASA.
