Singapore almost always takes 1st in international test scores and their long time leader didn't pull punches
and it's not an income thing, the poorest whites and asians score as high as black students from families making 200k+ a year

So in a way you're right, US government does run their education system very well, it just seems to be a racial thing which can never be spoken about politically so it's just ignored as the elephant in the room
