There's a simpler way to re-frame your question: Prioritarianism
Or: should we help the worst off at the expense of everyone else?
Most people will answer no. Mostly because this is a race to the bottom. And in a framework like education, you risk a slippery slope of making the bar progressively lower.
Left wing politics tends to focus on egalitarianism, the needs of the many outweigh the needs of the few. This is the current school structure. Both the bottom and the top students get lower quality education in order to provide the best education for most. It is a logistics problem.
But your framing is bad. It need not be a zero sum game. We can lift the floor without costs to the middle or top.
