As a matter of fact yes.

To have been in a country where there are "high" minimum wages, the low value added jobs are the first going away because they're too expensive for what they are.

The opportunity cost of a service is the limit for which one would be expected to pay for it. If forced to pay $1,000,000 to have someone clean your bathroom, you'd end up cleaning it yourself.

Grocery stores have something like a 1-2% margin, and people are often price-sensitive when shopping for food. So they'd have trouble raising prices. Probably they'd try to depend on self-checkout machines more. I imagine fast food companies like Taco Bell would lose sales.

High-margin software companies wouldn't care about the cost of their janitors, like you suggest.

Yes. The telephone sanitizers become too expensive, dooming us all:
