I don't think that would help much. Let's say you have 7$ minimum wage in one state and 10$ minimum wage in a neighboring state. I would think it's very likely that more low end jobs get created in the 7$ state compared to the other. However, if all states have a 10$ minimum wage then there's no easy substitute, except for going to another country, but that's much more complex.
