The Soviets did that. They channeled kids into various jobs from kindergarten onward.
My experience in the current U.S. as a retired corporate professional who tried a lower-stress job after retirement is that people who excel are subject to discrimination -- regimented employees bully and hate an achiever, and accuse them of snobbery and "not knowing their place." When I would try to introduce any commonsense improvements that actually worked and boosted performance, especially if it made things look better to the regional manager, the knives really came out.
