Lots of people want to work in game development. Lots of people do. Some people say game devs are underpaid. I tend to think that they're paid what they agreed to accept and that is based in large part on market forces (supply and demand, value over replacement, etc.). I also left game development because it wasn't for me long-term. (I was underpaid relative to what I could make in another industry, but I wasn't underpaid by my game-dev company. They quickly hired a replacement for me, I'm sure.)

A company like Google, paying substantially over minimum wage, is probably not underpaying most employees systematically, almost by definition IMO.
