I agree, it's sad that people don't receive at least min. wage. I mean, min. wage is still not a living wage but if they got tips on top of that...but the other person is right too, if prices are raised to pay everyone properly, many people will stop eating out as much.
It's sort of a no win situation. I don't like that tipping is expected to be part of their basic pay, I liked it when it was a reward for excellent service. It's not the servers fault that they aren't paid properly...I do tip 15-20% when ever we eat out.
