although they can probably mitigate the effects by moving to one of their 500 houses that's in a safe zone

That's why they don't care.

Climate change hits the poorest first and hardest (see: hurricanes in the Caribbean and SEA).

Billionaires can fly in, enjoy the sunshine, fly out and not get a drop of water on their skin.

And they'll keep "outrunning" climate change on an individual level, and only feel it when it hurts their net worth*.

do the billionaires not care about their own children?

Ummm...no? I sincerely believe some people are inherently evil. Look at Elon Musk and how he treats his children.

I was watching a documentary on the nature of evil. There is an incarcerated serial killer who acknowledges what he did is evil and wrong, but he doesn't feel empathy. CT scan of his brain showed that the part of the brain associated with empathy is not really active. Having said that, I heard that the longer someone is in power, the more that their brain physiologically changes.

Of course it is more complicated and nurture still plays a role on the person's development, but I think sometimes nature is stronger.

They have bunkers, they have stockpiles of food and medicine, and they have staff to maintain it all. They fully believe they have the means and resources to insulate themselves from all consequences.

If we dont get rid of capitalism, rich will be the last one to be affected by climate change. Proletariat is as shield for them to face wrath of climate change first
