Sure, so let’s try nothing, because the current system works so well.

Not where I was going with it. There are definitely a lot of things that should be done, especially in the US, which I wouldn’t even call socialist, just common sense (like universal healthcare). But you can’t tell people “you’re not all equal” and suddenly they all believe it. That’s why most socialist countries were also authoritarian. Maybe over many generations of progressive change things can go differently.
