Another thing, people are bringing up "other software jobs" and that is a fair thing to do, but lets not act as if all products are created equal either. How many industries rely on selling a product directly to retail or DD for entertainment consumption? if you are a developer at autodesk, you are making more than wokring at a game studio, sure but you are also making a a product you will sell for $3k per license to thousands of studios, colleges, freelancers, etc etc around the world, just for example.
Different economics of scale
What are "resources" if not wages,benefits and OT?
And that's also my point. maybe the reason why there is a little "B tier" market is because there is no B tier wage. if every studio is paying employee wages consistent for cost of living in some of the most expensive places around America, how could there be?
