In my opinion instead what the open source does not get back in a fair amount is money I'm not really sure what the problem is. I don't know the numbers, but I expect there are thousands of full-time open-source developers. (I was one of them.) Meaning that anyone who has made a substantial contribution to an important project could probably find a decently-paying job to work full time on the project. There have also been a number of very successful startups based on open-source efforts from the founders.
