I disagree. A better world might be possible in the short term, but it only takes a few generations to forget the motivation to do so. It's the whole reason history repeats itself.

Anti-vaxers are a great example of this phenomenon. People haven't experienced how horrible stuff like polio is, so it's easy for them to dismiss it as not a big deal.

The biggest issue is that there are people with personality disorders who lust for power at any cost, and they're often charismatic enough to fool enough idiots into going along with them to achieve it.

Add in the fact that most people have no desire to rock the boat as long as they're comfortable, and you have humanity's Great Filter.

Sure, we can throw off the chains, but these people will chip away at it for decades until they can do it again. It's a cycle as old as written history.

Getting fucked hard enough that the world becomes better sounds like the best possible solution I could imagine.
