If there was no greed or self-importance...... communism, or socialism, might actually work.
However, there has to be someone to make decisions. That person feels they are WORTH MORE. Therefore, total equality is impossible.
Also, there are those who will do nothing but live off of the work of others, such as is happening now.
We are meant to help each other to stand up and be counted, not to “help ourselves”.
I think you're close but not exactly right. Even mere self-interest, as distinct from greed, is incompatible with collectivism. I'm not greedy if I want to receive the fruits of my own efforts, less a very modest percentage to fund essential state services.
