What I really think it comes down to is this: sports provide excitement and drama that nothing else can, not 24, Alias, Lost, etc. It is this excitement, this passion that these players show when in uniform that make them worth what their team chooses to play them. Some of you have said that living in a city you have to pay for these stadiums etc. I assume by way of taxes. Well what if I said that I didn't want to pay the Social Security tax (when i go to college and get a job), and I wanted to keep it for myself, because all the older people will break it down before I should, hopefully not, ever need it. That would never happen.
This is kind of off topic so I'll limit myself. There are some really great and honorable people in the sporting world. REggie White, Michael Jordan to name a few. But I see it as you saying that these men would be mature and these 18-29 year olds (approx) are not. Well to give you a story on my favorite sports team, Washington Wizards, Gilbert Arenas just decided one day to take 200 children to see the Spongebob Squarepants movie. He adopted a child who had just lost all of his family and posessions in a house fire. Yeah that's a really whiney ass grown up kid ain't it.
