I think cancer is a better analogy.

Like cancer cells, billionaires are part of the system that just keeps on trying to grow and hoard all the resources, hurting and damaging the organism

I'd say in general sure, but I've known some CEOs of small companies who really do care. They just never make it to massive companies, probably because they aren't willing to do the horrible shit needed to "take it to the next level."

In our healthcare system they're talking about refusing non emergent treatment for people without insurance until they get Medicaid, which can apparently take a month. This would save about 20million, which is strikingly close to what Propublica reports the system pays in executive compensation. In other words, if the money is THAT important, we have a way to save that money without literally denying cancer care (time is a factor). But reduction in executive expenses isn't on the table. Fuck these high earning sociopaths.
