Here’s the thing: There’s enough variety to human existence that there’s probably no one system which could work for everyone. With every society which has ever existed, there are those who consider it perfect (or close enough) and have trouble imagining it not being perfect for others. Then there are those who merely consider it okay, or those who don’t like it but aren’t willing to rock the boat much. And then those who will hate it, and end up getting sacrificed in some sense in order to keep the system going, making them hate it even more.
The goal of progressives is to create a society where, whatever other issues there might be, no one is inherently disadvantaged due to race, gender, sexual orientation/identity, religion, social class, etc. We do not live in that society yet, nor do we have any good answers for those who aren’t comfortable without the existence of a “lowest class” which they can feel superior to simply by not bing part of it, particularly since such people would effectively be the “lowest class” under a truly progressive society.
…Also, your idea of “love” is kind of nightmarish to some people, and always has been, despite how it’s often been glorified in pop culture.
