It’s rich guilt.
BTW, don’t feed into Marxism with that “working class” nonsense moniker. It’s both insulting and inaccurate.
There are two old great books on this topic:
https://www.amazon.com/Anti-Capitalistic-Mentality-Ludwig-Von-Mises/dp/1467934836
https://www.amazon.com/Envy-Theory-Behaviour-Helmut-Schoeck-ebook/dp/B07WRGFYDH
Von Mises book is most relevant to the “rich kid” syndrome.
The “rich kid” knows deep in their heart they are a “useless eater”, a non-productive human who offers nothing to his fellow man.
They strike out at anger at everyone around them.
The cure—hard labor. Even if they are picking a crop they are adding some value instead of leeching off their rich parents.
More like it's a way for the already-r8ch to stifle competition from arising from the middle class, who could compete against and supplant their own loser offspring.
