Why do the superrich spend most of their time around their own types. Would it not be much more fun to hang out with people who didn't have their level of wealth so they could really show off and everyone would come out better.
Bragging about your new $700k sports car or $10m yacht to your super-rich buddy who last month bragged to you about their new $600k sports car or $9m yacht is much more likely to be enjoyable.
Plus in the real world it's not just about bragging. Believe it or not super-rich people have problems too, and they are problems that only other super-rich people are likely to be able to commiserate with them about.
And in general, members of any group -- computer nerds, artists, dock workers -- tend to hang out with other people from their same groups because they speak the same language and have overlapping experiences, etc. They "get" each other.
that's not a bad thing.
