The interesting thing about today is that the rich don’t have access to better technology than anyone else due to massive scale. Also, they have no leisure time...
I think it depends which rich you're talking about. Certainly some of them seem to have plenty of time on their hands: https://www.instagram.com/rkoi/
I wonder how many of those kids rent cars, clothes, etc. to look rich. I mean it is Instagram after all.
Probably some, but the point is just that there's a difference between the working rich and the idle rich. Obviously it's not a black and white thing, but someone who becomes a millionaire after working their butt off for years as an entrepreneur and selling their company is having a very different experience of life from someone who inherits everything and whose only experience of business is as a figurehead— there are lots of examples of this, but current populist premier of Ontario Doug Ford is a good one. Jared and Ivanka are probably in this bucket too, though perhaps to lesser degrees.
There is a leisure class, but it's more like the top 0.1%.
