1. Most of the devs are employees, who do not "sit on their money". They have to work for it. Hard.
2. A company has expenses. Quite a bit. They have taxes to pay, Steam wants their 30% (or whatever it is) cut. I would not say that IronGate is broke, they're now well funded. Nothing more. Most Indie startups are not that lucky. Most indies fail. Hard.

So, it looks like you don't really know what you are talking about.
