The people who cook for them, the people who clean for them, the ones who take care of their kids, the one who sell them stuff or serve them in restaurants...

They have separate kitchens for the prep, the cleaners work while they’re out on the yacht, they have people to do the buying, and the restaurants they visit have very well trained staff who stay out of the way.

All that is irrelevant to the point: they still need to have those poor people around them, trust them, and even trust their security to them.

And this is all very easy to control.

First is you get a particular group of people to work for you. You tell them they are better than all the other poor people out there, that is get them to be nationalistic/racist, etc. You also give them a little bit more than the abjectly poor so they have something they fear to lose. You also let them know if they upset the situation they are in retribution will be swift and brutal and affect anyone they know and love.

And this is how every societal hierarchy is structured.

So easy to control that most rich people throughout history were murdered by their guards and close helper circle.

"Most rich people that were murdered" is a different statement from "most rich people"

Epstein had a staff of 70 on that island kept mum

Also, they're not building the house or the jet, they're not growing the food, ... people close enough can be chosen for willingness to be sycophants and happiness to be servants. Unless you're feeding yourself from your own farm, or manufacturing your own electronics, there are limits to even a billionaires ability to control personnel.

nah, if slave owners like Thomas Jefferson and George Washington could reorient their entire lives around not seeing the "ick" of chattel slavery I think modern billionaires can do the same thing even easier now if they wanted.
