This is the least dumb example of this logic that I've seen. The root problem seems to be that minimum wage enthusiasts don't understand that the minimum wage is only for people with no skills and people with no skills are trivial to replace.
The minimum wage is a price floor on labor and labor that can't deliver the goods will be unemployed because the true minimum wage is $0.
Also, the black market. Not the illicit one, but babysitting and lawn mowing.
