Yes, and for countries too: most large countries are controlled by psychopaths, eg Putin, Xi, Erdagon, Bolsonaro, Trump if the coup had succeeded (maybe next time).
Whilst smaller countries are more often somewhat well functioning democracies.
The more layers of power one has to climb to get to the top, the more beneficial it is to "be able to" happily manipulate, step on and destroy others
Actually it's sometimes a helpful feeling -- or evolution would have made it disappear.
But yes, many people feel shame too often? In a non constructive way,
At the same time, consider this: You're trying something new, maybe singing karaoke for the first time. It doesn't go well, you sing the wrong tones, the wrong lyrics, and the others start looking at you with surprise and a bit disappoinment in their eyes.
Should you continue singing more and more songs like that, they'll start to think that you're clueless about the impression you're making on others. They can start thinking you have some minor mental problems (if you sing bad enough and go on and on happily).
But instead you feel ... Shame, and withdraw: that day you don't sing more karaoke songs. Back home, you practice in the shower, and two weeks later you try again an now it goes ok.
> so they can hire the laid-off from other companies
They don't only hire recently laid off people. Most people who apply do that for other reasons I think. Also, maybe eg Google s recruiting accuracy is better than other companies lay-off accuracy
