What depmats said. Notice that, except for the NFL, there aren't hardly any professional sports on broadcast TV these days, because cable channels are willing to pay more--they get revenue from viewer subscriptions, not just advertisers. Eventually things will get too rich for the cable channels too.
The problem with any argument that certain people get paid "too much" is that it boils down to, "well sure they found somebody willing to pay them that much, but, you know, nobody really
deserves that much money." And things get ugly if you start following that kind of thinking to its logical conclusion. (Ugly if you're into free market kinds of ideas; if you're a commie it doesn't look so bad.
) A letter writer to the Phliadelphia Inquirer recently wrote to that effect, saying that the Philadelphia Orchestra shouldn't be paying a percussion player $100,000 per year. You could start with many professions.
