I don't doubt the incentives. People should simply know what they're getting into. When 85%+ of youth players don't have any shot of going pro, yet end up with lifelong injuries that fund entire medical careers...the tail is wagging the dog. You can't make smart decisions without information.
There are inherent risks in playing football.
The schools/sports programs have to carry insurance for their players. If playing on field turf presents considerably more risk of injury than grass, the Injury Insurance Policy rates should reflect that.
*Also, in your first post you said "kids destroy their bodies chashing their parents' dreams"
Where does that take/viewpoint come from?
Most kids are self motivated to play the organized sports that they love. The chance of landing a D1 ride, and possibly playing in the NFL are the things that fuel the hard work, and sacrifices they go through to play football.
a$$hole parents, and live through their sons dads exist, but not enough to say that kids who play football are chasing their parents' dreams.
