How many hours a week are these people putting in? As a senior-level developer in the midwest, my pay looks paltry in comparison and yet I bet you I live a much more comfortable lifestyle overall--zero debt, a decent work day in a calm environment and decent time off. If your cost of living is so ridiculous that you have to pay people 50-100% more than pretty much the entire rest of the continent what have you gained?
