It's not even necessarily up to the founders. In a VC-backed startup, the VCs make the call when it comes to compensation ranges. There is little diversity between companies on how that actually happens. We can pretend that it is a market equilibrium, but the analogy I would rather use is that of the medieval professional guilds, where prices were often rigged for the benefit of those at the top.

I am not claiming that the VCs are evil, or even a necessary evil. I don't think they are evil nor necessary. I think that they may be very inefficient when it comes to providing for a healthy economy that benefits everyone and not just themselves. Hate the game, not the player.
