A better question would be what wasn’t ruined by rich people?
Aside from everything? The internet.
The environment
Everything. They don’t care about nothing but making more money. Greed will be the death of everyone who isn’t already rich.
I’m going to say dog breeds
frantically gestures at everything
Climate.
It depends to what you mean by “rich people.” Yes, climate shambled by the global north, or the to 20% richest citizens of the planet.
I agree that big corporations bear a big burden for climate change, like, for example, Exxon which knew about CO2 since the 50s, and tried to hide it, and lobby against any regulation.
But saying that, us the 99% westerners don’t bare responsability by buying a new iPhone every year, is a lie.
Given that the corporations own the politicians who make the laws that structure our lives and allow planned obsolescence and a lack of transparency in things like phones, still going to put 90% of the blame on the rich here. Your perspective might be correct in a functional democracy, but that’s not where most people (nor even most Westerners) live.
