Thats fair, I didn't go that far down to verify the funding, in my source it only said it was conducted by Lloyd Corder, an adjunct professor at Carnegie Mellon University.
I can accept that the industry shapes the narrative, and pointing out who funded this one is doing exactly that.
But it was only one of many, and I will die on this hill: everyone I know does not want to stop making 40 - 50 dollars an hour, and they KNOW that will happen. They worry they will work longer with worse shifts.
Every single restaurant that has tried this in cities I visit has failed. The good servers and bartenders go where the money is.
Personally, yes tipping needs to go away, but everytime I see it tried, it fails.
And I believe the overall quality of life would be better without tips (health care, security, etc) and I don't want them. Hopefully we do get to that point.
The one thing I keep thinking that would have to change for the US: universal health care and paid time off.
Security would make the workers better off. But good luck getting that.
