A system slanted toward the rich

There are 351 D1 teams with 13 scholarships each = 4563 college basketball players. How many of those realistically have even an outside shot at the NBA? And yet the whole system is geared toward teams that are able to attract NBA talent who for all practical purposes never have to attend class. Why are those players even in the college game? They do not want to be in college, or they would stay in college. Why do we make them be in college? And the players who do stay in college, go to class, stay eligible, and who learn the game and work as a part of a team to win games - they are penalized by a system that only really focuses upon maybe 1% of the college basketball population. The system is broken!
