I have an in-law relative who works with high net worth individuals across W. Europe (say 10M Euros and up). His role is tax advice, basically reduce taxable investments from multiple sources from multiple countries, all within the laws of each nation and the EU.
He said most of his clients can walk on the street without protection as they won't be recognized. They aren't flashy, don't use social media or use it very little, we're talking young to old. Money is a great attractor for trouble, then you need bodyguards, super techy alarm systems, bulletproof cars, etc. These high net folks vacation like normal people, eat and live like the average person, and drive the EU equivalent of a Ford Crown Vic, wear department store clothing.
As a result, my relative has adopted the same habits. He said he would not need to work for 20 years. He only works as long there is a technical challenge, thus very specific contracts for a few months at a time. He often takes months off. He doesn't drive a car as he lives in a major EU city with excellent public transportation. He's said he has a lot of clients who don't own a car for daily use, but may own classic vehicles for weekend drives.
When the Panama Papers were leaked, he wasn't surprised. He said that he recognized several names; he refused to take them on as clients as they wanted him to bend/break the laws for tax restructuring.
TL;DR: You work for people with a Mustachian mentality, you end up adopting their values.
