This is one of the best reasons to socially stigmatize wealth hoarding, even if you can’t change the fundamentals of the capitalist system that causes it in the first place.
If enough people make people who hoard money feel lesser than, to the point that having less is a preferable alternative, then they’re more likely to give away their wealth and become at least a little bit less shitty people.
This is also, coincidentally, why rich people isolate themselves within bubbles of similarly rich individuals, who won’t look down on them for being so greedy and narcissistic.
If you have any family members who still play the “I still think Trump is doing what’s right” card because the media they consume has managed to spin every possible event as positive somehow, ask them how allowing a known cancer-causing chemical that directly financially benefits Russian corporate interests is beneficial to this country.
If the media can find a way to convincingly spin this as a good thing, I’d be shocked. Not that shocked, but shocked nonetheless.
