It's the same mentality that your neighbor has... I don't have enough because someone else has slightly more than me. Tony across the street got the new car... so I should get a newer and better one than him!
The .01% only hang out with each other, and they compete with each other. And they get jealous when their buddy has a cooler nuclear bunker than them, so they need that extra 10 million this year to ugprade their bunker.
They are not evil, they are just people. And you'd behave exactly the same way in their situation. It's how we are wired, to be stupid selfish jealous monkeys. You don't exist to them, they are not thinking about you, only about themselves.
Same thing when you go to your town meeting and your elderly neighbors are screaming bloody murder at their taxes going up $50 this year because they think children should go to school in unheated buildings.
