Not to forget the times where states raise their minimum wage and see the number of people in the labor force increase. The balance of power is almost always squarely weighted on the side of the employer. This can push wages below market optimum.
I’d expect minimum wage increases to be mostly off the table during recessions, so it’s not surprising to see them passed during economic expansions, which are tightly linked to rising employment figures, so this might be a "wet streets cause rain" correlation.
