Workers rights were not generally gained by moving jobs, it was unionization and protest. Moving house doesn't change the market unless everyone else does it, and even then, the major benefit would come from something like large numbers of people agreeing not to max bid (i'm not suggesting that such a thing would be realistic, but it's an example of unionization)
