I think the real loser here ends up being restaurants wondering why they can't get people for 2.15+tips
Back when I was in college I took a job as a stock clerk at Publix, I got paid more than some supervisors ($12/hr in 2015), but my god was that the hardest job I've ever had. You're basically lifting for 6-8hrs straight.
I heard a report on NPR a few weeks ago where they were lamenting how much servers make and we’re basing their data on reported income to the IRS. Hah.
I believe servers get taxed at a certain rate regardless of if they actually make the tip. It's assumed they will make $x in tips so they are taxed for $x regardless of if they made that or not. They get hosed on both sides (employers and government).
I was working 2x 20hr/week jobs and making less than her working a Fri/Sat/Sun..
Anyway, most of that in principle was cash tips. She was young enough where she was getting all of her tax back anyway, but I do know many people who underreport the tips they receive.
People are not willing (apparently) to give up a sure-thing like high-paying fulfillment work or enhanced unemployment benefits in exchange for an unstable position like making $2/hr and hoping patrons throw money at them.
Restaurants have to pay $15-$20 an hour to have a consistent and reliable workforce in the current market.
Megacorps like Amazon can whine as much as they want that they're "running out" of employees, but the solution is obvious: just raise wages. Once big employers like Amazon start feeling this squeeze enough, they'll start passing the costs on to consumers, and eventually even those Chinese imports will start becoming more expensive. Once that happens, it becomes impossible to pretend that inflation is not real.
Plus, recall Keynesian feedback loops that more wages will unlock more consumption -> more wages. So increasing the wage share can even make the rich better off, unless the rich cruely only care about their power relative to the poor.
Anecdata: At a McDonalds in an urban center in Colorado they're offering minimum 17.25.
