You're literally describing equity. The more interesting question what option will you choose when you're told that individual interventions as you describe are so expensive as to be infeasible.
I don't think it's an issue of a person's politics, Republicans tried the exact same thing with No Child Left Behind. Is the more important thing the individual rising to their highest potential, or is the more important thing the system where economic factors
have created a cycle where only children of middle-class or better families are given the environment to rise and those kids run with the flywheel and become the middle-class parents.
I was literally never not going to be successful, I think I'm reasonably intelligent but that by far wasn't the biggest factor. My parents made damn sure I was on the gifted track, always got A's, and was set up
to get into an in-demand major at a prestigious university. Was I actually that special or was I just the chosen one, in that I was chosen?
You can only be like "that's not true of everyone <anecdote>" but the exceptions fall away in the aggregate where your success is frighteningly well predicted by your zip code.
