*growstuff * - I didn't really know what rentier means, just guessed renter (wrong).
I've looked it up and it means annuitant ie receiving an annual income from an earlier investment.
Which could also include people like me who paid into a local govt. pension scheme while I was working, and now retired have a LG pension.
Until the investments that the Council made with my money stop giving returns.
Strictly speaking, yes, but in practice, no. You've paid for your pension. There are people who live of interest and rent for the whole of their lives, often because they've inherited it.
We have (or have had in the recent past) a situation where people can make more money from the appreciation on property prices than the vast majority of people can earn from going out to work. At one time it was possible to get mortgages with very little deposit. Inequality is compounded by inherited wealth and investment in property diverts money from investing in production.
