There’s no reason you’d have to raise the minimum wage at all. You would have to get rid of the exemption that allows certain eateries to pay less than MW, sure.
You wouldn’t have to raise the minimum wage for the same reason why other highly in demand workers aren;t effected by a minimum wage- they already get more than a MW, so changes in MW don’t effect them much. I figure I get paid something like $40/hour thus, a change in MW doesn’t effect my salary at all.
High end restaurants, in order to keep the best waitstaff would pay their staff more or less what the waitstaff gets now- including tips. They’d raise their food prices a bit, but the gross check- after tip- wouldn’t change much for the average consumer. Why should it? The prices go up 15%, but you don’t leave a 15% tip- the net result is just a small increase in the sales tax.
Waitstaff in the high end restaurants would net slightly less, as it’s a open secret that few report and pay taxes on all their tips. Having them pay their fair share of taxes doesn’t both me a bit.
Where the problem would lie is in the cheaper coffee-shop type eatery where the waitstaff likely net less than MW. The nessesary increase in lunch prices might drive a few of those out of business.
Buffet type eateries- where tipping is uncommon or *de minimus * anyway- wouldn’t change at all. Those are becoming more and more common, and there’d be a few more of them after the change.
Overall, there’d be just about as many net jobs, with just about as many businesses. The net pay would decrease a tiny bit due to more taxes, and the net bill would increase a tiny bit due to sales taxes. Neither would change things much. Service would decline. I’ve been to NZ, where there is no tipping, and the service was terrible. True, in America you tip after the Service, but a good waiter will give better service knowing that in the long run it leads to better tips.
Of course, it could be UnConstitutional to actually prohibit tipping- it could be argued it’s an excercise in Free Speech.
