The practice of tipping will go away if enough people stop doing it. If they still want to have people working for them restaurants will be forced to raise their wages. And if people will still tip it's because of the excellent service, as it should be.
I don't think I can stop myself from tipping in America. I used to make more than waitstaff when I worked at Arby's, let alone now when I make ten times that. It's been ingrained into me since childhood: "If you can't afford to tip, you can't afford to dine out." Waitstaff make $2.13/hr without tips -- that won't even pay for an appetizer. I don't want to anger waitstaff. They can poison my food. They can stop me at the door. If I'm not tipping, they have nothing to lose by beating me up or trashing my car. Is mandatory tipping a good system? No. However I won't suddenly stop paying at least 20% for service until I know that server is getting at least double minimum wage. That's a hard job and I'm a softie. If you really want to end tipping, you'll have to come up with something better than "let's not tip". Perhaps starting a chain of restaurants where the waitstaff earn proper wages and only eating there for a while...
