What if the job can be done by an engineer with a cost of living where $15/hr is viable and profitable? All this will do is drive clients to another marketplace where there is no "minimum wage." There are a ton of reasons to hire a local developer and tons of reasons to hire a foreign developer, and an American developer probably doesn't want the clients that can only afford $15/hr anyway.
