People are innumerate/irrational and cannot understand the difference (or lack thereof) in pricing at restaurants that do not accept tips. See [1].
I've become convinced that the only way tipping is going away in America is if it is made illegal.

The good news (?) is that tipping in the US has strange sociological effects that make it a good target for legislation. It has been found that various groups are more or less likely to A) leave a tip and B) receive a tip. That makes it pretty clearly a discriminatory practice.
