Yup, my fault, not clear enough. I'm talking about the US more than the UK, although now that UK universities have essentially been told by the government to behave like businesses, with poor people already less likely to apply than the rich since fees went from zero to almost ten grand a year in the course of a decade, I expect the UK to catch up soon enough in terms of buying your way into a good university (there is indeed already rumbling about places going to foreign students who can be charged far more than home students, establishing the principle, so I expect that as soon as universities work out a way to let people buy their way in, they will).

Edit to answer this point below: ""Give up, no point working hard, you will never make anything of yourself, the game is rigged"?"
No. My alternative narrative is "know the game is rigged". If you're playing a rigged game, your chances are so much better if you realise this (hence my very first post here - the people who rig the game work hard to make the unlucky ones think it isn't rigged).
