CP Mary consistently nails it, IMHO 👌🏻👌🏻.
Re rich, powerful men surrounding themselves with glossy young girls who are supposed to be grateful for dinners, frocks and jewellery, I think that is definitely still a thing in some circles.
consider, for example, the endless "yacht girls" on the Riviera etc, doing apparently little but being decorative and getting snapped by the tabloids or celeb magazines. Also, sugar daddy websites, where the dinners, frocks, lifestyle are the whole point from the woman's side - the money and power on the man's.
Don't get me wrong - I am totally not condoning it, and it's very much not my scene. But it is a thing.
