It is certainly not socialism nor commune life where everything is apportioned evenly.

However, it works within reality in this world that some have more than others, but generously share to elevate the poor.

That people didnt care only about their own group (party), but for the whole group (state).

IOW, people caring about other people, even those not at all in their group.

It isn't necessary or realistict for humans to always share evenly with the rest of the world, regardless of effort or natural skill amongst all. That's not how humans are hard-wired. Humans are naturally competitive. Without extra rewards people will seldom make any long term, extra effort to do better than average and then share it with those who don't.

However, humans will share with those in need and do care for the whole when no one is attempting to separate some from others.

I suspect that part of the equation is why you don't see the same brotherhood that we do.

I oppose socialism for that very reason. However, I am okay with Democratic socialism that rewards hard work but also cares for the "least" amongst us.
