The money is crap in games. You don't go into the industry if you want to make lots of it.....if that's what motivates you then you can get more of it, much easier, in pretty much any other industry.
If people are the industry for the money, they are the ones that need a sanity check.
That doesn't really dispute his comment. People work in the game industry because it pays, as it does in with any other job. This doesn't mean they have any real interest in the what they are producing. This is evident in how many Battlefield developers actually play their own game, it's not very many.
