Now then, yes, college should be free. We are one of the last nations in the world that still charges for college.
To those who say that taxes would increase, that's just nonsense.
1) The government doesn't care how much money is coming in through taxes. This is known as a deficit.
2) Our military budget is 10x the rest of the world's combined. This is not an exaggeration. If we dropped this to 9x, not only could we give free education to everyone, but we'd probably cut a big chunk out of our deficit spending, which would be great, because we really shouldn't be spending this much more than we make for extended periods.
3) We're already offering tons of money for people to get a college education, it really wouldn't take much more to make it all free
Frankly, I'd rather see science spending go up first. The NSF budget has been cut AGAIN, and the entire science world has subsequently felt the pinch. This is not good. US research is dropping off rapidly, and pretty soon (maybe 20-30 years) we'll have to buy our non-military technology from other nations just as other nations had to buy theirs' from us.
