Stronger morals, perhaps, but also redirecting the collective moral compass from favouring the individual to favouring the collective. Today, one can feasibly frame working for a megacorp for $$$ as morally just to provide one's own family with a comfortable, safe life. Morality focused on the individual.

Things like effective altruism seem to be an attempt at redirection, but they have their own problems. Until someone or something succeeds with redirection, having stronger morals will only make the problem worse.

Moral high ground is low intelligence.

This is just yet another "if people would be just so" brand of wishful thinking.
