I don't care where you live in this world. The cost of living is going up everywhere. If you pick up a cheap developer, expect the person is going to be hitting you up for payments regularly. At this rate, the person can't really save to get ahead, he is likely struggling from one payment to the next. Getting screwed over would probably be devastating to him, though I imagine he was more concerned about quick payments than getting screwed over. If you have someone doing cheap work and doing well, keep the payments flowing. If you are happy, then make the developer happy as well.
