Rich corporations and the large group of taxpayers depend on getting the most thorough development of talented people, so they should pay for it entirely, instead of the self-financed development primarily of the talent of the upper class, who will subconsciously or openly use their development to enhance the power of that class, especially since they owe their education to their class privileges rather than to their ability. So subsidizing all people with talent will create solidarity within the new class of talented people.
But most important of all in overthrowing the present anti-talent system is that this begs the question by assuming that not to have to pay is enough. A society that immediately and materially awards students for their achievements will awe the world. School is work without pay, and work without pay is slavery or indentured servitude.
