Those that should be tipped are those that are making less than minimum wage and the expectation is that a good portion of their tips drive them to a minimum if not better wage. Depending on your jurisdiction, the number of people that make less than minimum wage might equal zero. In Ontario, for instance, your server isn't reliant on tips to make up their wage, so you don't need to tip them.

The change to a culturally post-tip environment has dragged behind the legal scenario where what we're doing is tipping when not required and this avoids the end situation: workers individually or collectively asking for wages above minimum for the work they do. If, with tips, a server was making ~$20 an hour, when the legal situation removing the need for tipping happened, people should have stopped tipping, and the servers should have asked for $5 wage increases with tipping disappearing.

I'm afraid we're going to see tipping around for a while, and expand into areas you should never tip in (grooming unless the worker rents a chair - which I think is a terrible business) unless a government goes bold and says "that's it - no more tips."
