IMO most of the yelling comes from parents that have not spent tons of money on club ball. The club ballers, in general, know a good tackle from a dangerous one, even when it is against their kid. There are of course, very loud exceptions.
I find the thousands comes from playing for clubs. Insurance pays for the injuries, but they're not interested in helpding with the costs for the 90 min drive to practice, not the tournament in Flordia.
