I don't like Fox at all. The network has consistently been run by greedy morons (to oversimplify).
However, each of the actors make about $500,000 an episode and about $8,000,000 a year.
I personally think that's way too much. I know there are more corporate assholes out there making bonuses that can't be justified in the slightest, but that's not the topic.
Now, as we can see, Fox is pretty much ignoring Shearer. They've had a fucked business model for years and now that the economy is in the toilet, it's starting to present itself. The reason Mr. Shearer hasn't received any answer is that they don't have one.
