nah, because I don't need anyone to do those things for me.
on the actual question: I doubt any of these games pay a real salary for their programmers UNTIL the game hits big. which means the real work is already done for free or for a symbolic fee by the time there's enough money for actual salaries.
I've seen a couple of projects where people wasted their saving on hiring for real from the start, but they go under in months while even in best case scenario you only begin earning maybe after 2 years of development. if you're super lucky, because other things than funding will kill your game before much more likely.
