They are or they aren't, they don't become sociopaths in certain situations. My take is people accustomed to wealth from birth just don't understand how hard it can be.
I used to work with a guy who was very well off. I was not. I suggested something for a fee, he immediately tried to bargain with me. It was little money and I needed it; it was nothing to him. To him it was a game. He was no sociopath, he just didn't understand hardship. I saw him do that quite a bit. I'm sure if he ever felt a hard pinch himself he'd realise it wasn't a game, be much more sympathetic, but... that wasn't going to happen. Genuinely nice guy too.
