I have literally no real knowledge of this subject. But - shot in the dark - the people saying "bring this back" are probably once again falling prey to an idealization of history. Similar to how everyone imagines themselves as princes and princesses if they were to live in medieval times, but statistically you would be a peasant living in a shit hut.
I imagine the modern corrolary would be - you and your bro went to an elite private school together, wearing sport coats to parties and sailing in the yacht club. You had a lot of good times together and bonded over getting drunk and talking to girls. Then the two of you got hired by the same elite New York law firm and became roommates. But while you were willing to work hard and keep your head down when you got bullied by the senior partners, he wasn't cut out for corporate life and got fired. So you started paying his rent, since his trust fund would only go so far. Now, 10 years later, you make far more money than you could possibly need, and just letting him live for free is worth his company since he's a pretty good sounding board for dealing with problems at work and with your girlfriend, and he's a good guest to bring to cocktail parties.
The part the "bring this back" people miss is that in order to benefit from this arrangement, you need to be known and liked by rich people, which typically requires that you are already rich. And I mean, you can probably live with your parents for free - it just isn't classy, since you aren't rich
