They start to move abroad. Seriously. Violent crime such as robbery at gunpoint in your own home, car jackings etc is an increasing problem which worry many in Sweden. It is perhaps not common but is increasing with a worrying pace.
That seems like such a middle class worry. I don’t see how people with tens of millions of USD (or equivalent of course) are more susceptible to opportunistic crimes like robberies and car jackings. If anything they are less susceptible since they can move to nicer places.
The question was, how do they act? And perhaps you have missed that discussion.
