It's from my experience with real people in real life. It's not a strawman. I've known people with high social status locally who wanted equality in money but didn't do anything to reduce their own social status or raise that of others. On the contrary, they sometimes maintained theirs by bullying others.
Where are the equality-wanters who want to isolate popular people from their friends and force them into relationships with people they don't like? I've never heard of that but it's the social equivalent of what communism is for money.
Somehow everyone responding seems to have completely misjudged what I said. I guess you've all been spending too much time on the internet.
When you're fighting strawmen you aren't grappling with the actual content of an argument you're purportedly opposed to, but it does serve the ego, as it's nice to tear down something you don't like but can't explain why.
