The system in developed countries allows young and talented players (students of colleges or students of schools) to prove themselves. A person who dedicates his life from an early age to sports has the opportunity to connect his life with the career of a professional athlete.
It is necessary to accept the fact that Sport in its various forms has become a way to make money. But if earlier it concerned "the higher league", now sports in college became a way of earnings for the organizers. It's business. The way to monetize the efforts of players and the interest of fans.
It is natural that where there is "big money" there is a blurring of the notions between the right and wrong. And where there are big incomes there are also big expenses. Often you can see the abuse of the system.

I liked that you gathered the facts together and brought the evidence. In fact, this is an investigation that opens your eyes to what is really happening. Many fans come to enjoy the game and get pleasure. Not everyone of them is able or wants to see in this trick. Before that, I was little aware of the functioning of this entire system. Now I know more. Well done, thanks. Interesting stuff.
