The issue is that there are more people who are talented enough to learn complex jobs than there are positions. So the system is built to make sure the children of the well-connected get first dibs on the available positions. No matter how well educated everyone is, we will always need more food prep workers than surgeons. In other words: the people in charge of the country understand that a lot of talent is wasted, they just don't care. And to make sure that working class people don't get upset about their class status they use the language of "personal responsibility" and "the land of opportunity". That way you make it seem like it's their own fault for being in the situation they're in.
