When you make reference to "a line would form 10 miles long of people who would readily step in their shoes", it appears you are arguing that others being worse off than they are somehow indicates that they are not being taken advantage of. But that's not really the standard. As I said, it's not mutually exclusive.
Again, yes they are better off than their but college football is also such a fundamentally different media product, did their compensation / benefits track with the explosion of college football's revenue explosion in both popularity and revenue? Not even close. The better question would be how their compensation relates to overall revenue, and how that ratio compares to other sports products that generate significant revenue. By that measure, they are still well, well, well below the mean, so it's not hard to argue that they are being taken advantage of.
