So what is your point? What are people supposed to do, not be wealthy? Not send their kids, who have to want to attend the academies and put in the hard work, to said academies because another kid can't afford it. You know what, I was one of the poor kids trying to do everything in their power to be good at wrestling...find rides to tournaments, figure out ways to pay for the tournaments, work odd jobs, wrestle and workout on my own, beg other people's dads to coach me, sneak into the school to use the wrestling mats, etc. That is what people mean by "chooses".
Not everyone is in the same situation financially...that is the way it is...reasons for it are numerous with personal choices being one of the main reasons...but you can't fault a kid who happens to be in a good situation financially and takes advantage of the opportunities afforded to them and puts in the hard work to become an elite wrestler.
