I pay $540/year for 2 in the Rockpile section. Granted, it gets more expensive as you move for a "better" seat, but with a value like that, its hard for me to believe that someone who wants season tickets can't afford them.
Hell, I was going to try to get some Bengals season tickets this year just to turn around and scalp, and the cheapest seats in the stadium (way upper deck corners) are $580/ea. + $450 seat license. Screw that...I guess I'll just end up buying my own section in the Rockpile eventually.
