Plutocrats like Thiel are constantly thinking about the fact that ordinary people vastly outnumber them and can kill them at any time. They think about it way more often than ordinary people do. It’s a point that they are acutely aware of at all times. It consumes their attention. They are always working on manipulating public consciousness to ensure that we don’t think as much as they do about how many more of us there are of them, and how we don’t have to put up with their domination of our society if we don’t want to.
As Michael Parenti once put it:
“I tell students when they say, ‘Oh they don’t care what we think. They ignore us’, and all that, and I say, ‘Oh no, no. That’s the only thing they care about you. The only thing they care about you is what you’re thinking. They don’t care if you eat correctly, they don’t care how your living conditions are, they don’t care that they’ve built up an inhuman and irrational traffic system that’s strangulating us and polluting our air, they don’t care about anything. The only thing about you they care about is what you’re thinking. In the morning, they start, ‘What’s going to be the story today? How do we manipulate, how do we control, how do we contain, how do we influence, how do we act upon what it is that they have in their minds?’”
Manipulating public consciousness is of existential importance to the ruling class, because no matter how many billions of dollars you amass, at the end of the day you’re still a soft skin sack of blood and bones like anybody else, and you share a society with huge numbers of people who can very easily hurt you if they want to. That’s why our minds are constantly being hammered with propaganda into accepting the status quo politics upon which our rulers have built their kingdoms.
This is the real answer. The rich know it's just like school shootings. One can trigger several in a short period and they're terrified of that.
They’re not worried only about stochastic terrorism. They’re also worried that we’ll become an organized & militant labor movement and gain some political power. Or worse still, that we’ll seize the means of production and depose them.
I agree with you but I don't think that last point is where this is going. There won't be any seizing of the means of production. That just isn't happening in America, and is arguable if it's ever really happened ever, anywhere. Power has transferred, but never to the people. However, they are worried that people have had enough of their shit. It's very difficult to start a revolution. It's much easier (as evidenced) to kill one guy and make the rest live in fear.
