Fair points, but perhaps let's look at it closer. Perhaps education has to be commensurate to people's access to information and the ability of power blocks to project influence. I agree that we are surrounded by knowledge and education, but we are also surrounded by disinformation, propaganda, marketing, adtech, etc...
I agree that people have never been as educated as today, but it was also much more difficult to project power over distances. Today, a fool in power can travel to the other side of the world in half a day and bully countries there into submission. More to the point, the fool doesn't even need to travel, they can do the bullying over a zoom call instantaneously. An extremely connected world with a vast number of feedback loops would need a proportionally more educated populace with much more robust foresight, no?
For what it's worth, I agree with your fundamental thesis that a lot of these issues are basic human nature, and unless that changes, anything we do will be highly ineffective. But we have to start somewhere, right? And it's much easier to sell a populist agenda to an uneducated populace who can only think forward 8 hours.
Consider this: people have been known to vote for increased taxes to pay for various public good projects. It can be done. Perhaps not necessarily on very large scales, because it's difficult to feel unity with people a 1000 miles away who are completely foreign to local concerns, but perhaps that's an argument for direct democracy. But direct democracy requires a population who is educated - at least in civil matters - and can put the long term goals in front of the short term pain.
