I'm talking about the class of champagne socialists. Those that constantly argue for higher taxes. They would have to contribute ore they'd out themselves as hypocrites. And these are people who live on their social status. They can't afford to be publicly outed as hypocrites.

then don't cut NASA's funding. Cut welfare and social security. Cut that which people may be inclined to donate to.
>if you give people the option of contributing (or not) to programs that they don't directly benefit from, they're not going to contribute much, if anything
and that's fine so long as the minimum is provided by the obligate tax.
