Just scored. Twice.
Well, many people who live here get good pension provision in the future, through taxes, of course. (something I think they'll soon have to wake up to, like France. Or, maybe not...)
Also, a lot of Italians, male and female, live at home with parents, grandparents, well into 20s and 30s till (sometimes never) they get married. (No rent) . And when they do, they often get an apartment/ house 'given' as a start-out 'present'. No mortgage.
I'm sure there are other reasons, too...
