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.
