> wages and don’t suffer from problem tips in the US solve (AKA, insanely low minimum wages in some states for tipped servers).

Well many waiters earn considerably more than the minimum wage in the US. In large part because of this system. I'm not sure why does the society value their work that much (in relation to most other service workers which is of course unfair). However, essentially what you're advocating is lower wages for some service workers just because the rest are possibly overpaid?
