You vastly underestimate the number of highly qualified developers in the world looking for work, and my opinion you vastly overestimate the value of your work. I would never pay your rate. Programming is a commodity. I hire PhD's from Asia and Eastern Europe for less than what would be considered minimum wage in the United States. An order of magnitude cheaper than what I assume your asking rate is. They produce great code and deliver in a reasonable timeframe. Calling this outsourcing exploitative is incredibly ignorant.
