Ah, the Roddenberry universe. I think that will begin after the cost of clean, limitless energy approaches zero. At that point anyone can turn dirt into a house or a hamburger so compensation becomes much less of a concern.

Just have to avoid the preceding world war.

For those downvoting Parents comment, in Star Trek canon, a 3rd world preceded the creation of a unified planet.

Turning dirt into hamburger exists already; it's called agriculture.
