Because 1) Taxes 2) Legal issues (much easier to deal with problems in a local jurisdiction) 3) In India, for example, there's a culture now that everyone wants to become a developer, because that's where the money is. It resulted in the markets full full of talentless hacks who took 3 months of some HTML/Javascript/PHP courses and call themselves programmers. I had to work with some of these guys, they truly don't get programming, and spend 10 to 100 more time to do anything compared to your average local programmer. Don't get me wrong, there are many talented programmers in India, it's just your chances of finding one are pretty slim.
