I don't think coaches looking at the parents to see if they're tall, obviously athletic, or a professional athlete is that bad of a thing. It's probably fairly universal worldwide that the big kid or kid with obvious advantages is going to get picked first.The sad undeniable truth of the American youth soccer setup.
It does amaze me that MVLA is so good - I don't think their athletes are that much better. It's the coaching and the style of play they enforce at all ages.
What's makes the US different is that coaches need to assess parents ability to pay to play. Other countries have Acadamies where anyone can play but only a few make it to the highest levels. The ones that make it to the highest levels fund all the rest of the players ability to play via a Transfer Fee when they're sold from local clubs to national clubs.
In theory pay to play should be able to provide the same type of player as the Academy model. In reality money twists and subverts everything + you end up with true talent on the sidelines watching less talented play at the highest levels.
