Yes, but they cant win capitalism if they apply those lessons though.

Eveyone needs it. Aristotle starts out his Nicomachean ethics stating that virtuous acts are first and foremost for the benefit of the virtuous person.

Platonic ethics should also really be taught widely, even more so than Aristotle's because they're easier to receive. Even if he has some hard to accept views such as that commiting injustice is worse than suffering it, everyone would benefit if children grew up with the notion that everyone does what they think best, and that those who do "wrong" things do so out of ignorance of what is good, rather than what we currently have where everyone knows what is objectively good, and those who don't do it are willfully wrongdoers and you just need to punish them enough and they'll become good.

Although you can have the best educational plans in the galaxy if the educarional system is crap. I don't know about the rest of the world, but where I'm from all education from primary school to a master's degree is just a bunch of information being thrown at you with 0 context and reasoning behind it, and when you're able to reproduce that information on demand (without any context): congratz, you're educated!

Should start in kindy, tbh.
