Yes, though they don't emphasize the doing-nothing. Further, it's easy for a wealthy person to mask doing nothing with appearing busy yet effectively being a socialite.

It may take good judgement, but not much effort. VTSAX and chill, as the kids say.
I grew up around the kids of very wealthy people, often multi-generational wealth. Most decided to have jobs. Some had very impressive careers, but when you realize that first opportunity was only because of a parental connection, suddenly it seems a bit hollow. It's not hard to appear wise and smart when you're wealthy, and then you can simply not fuck up and the rest of the pyramid keeps chugging along.
Case in point, Trump. He is a lazy fuck-up, but somehow managed to appear "successful" to a large portion of America.
