Dishwashers will be the only hit in restaurants. Wait staff is exempt from minimum wage laws due to tips being a part of their wage.
The biggest hit, and the reason this won't go away, has nothing to do with low wage jobs or the working poor. It is unions! Many union contracts and negotiations tie to minimum wages in one way or another. It is just like credit card interest and its tie to the prime rate. Buried in contracts is a clause that if minimum wage increases there is an increase in union pay.
TAB also hit on something that a few have tried to educate us on, but the media hides: All wages affect the prices we pay for goods and services. Consumer prices will increase due to this rapid and large jump in labor costs. This inflation will hit those who it is intended to help the hardest. It will also be like all other high inflation and actually cause a reduction in spending, which will further the cut back in jobs.
Think of this one:
We go to a restaurant, enjoy a meal and cocktails, and we tip well. A nice evening with the wife and another couple amounts to $300.00 (meal, tax, tip). We do this a couple times a month. Inflation hits, and prices jump by 25% due to the establishments added costs for housekeeping staff and dishwashers, plus a hit from their suppliers. Now we only go out for a meal like this once a month or month and a half. Instead of $7200 per year we now spend between $4500 and $6750. We go out less, we give fewer and lower tips, and due to the over all rise in prices we save the hundreds we don't spend rather than overpaying for extras.
