We're at where we are because of market forces. I doubt the market will "correct itself" when the market doesn't see anything wrong.
I'm all for better wages and labour conditions, but as long as that doesn't, happen, these jobs and services will continue to disappear. I hope people are aware of the fact that they're currently effectively voting for no fast food, no restaurants, and no theatres, because that's what they're going to get if nothing changes.
Higher wages will not be the solution I’m sure.
Or it'll be a "market for lemons" situation and someone will need to rewrite the rules of the market in order for the best thing to happen and/or it just won't get better.
When we can abandon this kind of thinking we will be able to solve problems again.
Ultimately, of course, the market will correct itself. If these service jobs are terrible enough, nobody will do them anymore, and those customers will just have to cook their own food, or accept shitty overpriced service from the few companies willing to serve them, and willing to pay employees enough to deal with that shit.
But it will be a loss to all decent people who treat people with respect and want to pay well for good service. If you want to keep those, your only option is to kick the entitled assholes out. Or you'll have no employees left.
