I thought the same, that we were a disenfranchised generation, until I looked at my family history. Mainly farmers pre 1950s. Mostly they married mid twenties and lived at home until they did so. The women married and moved to their husband's farm. If the man came from a family with more than one son then the eldest usually stayed at the family farm to work alongside dad, then took it over. The younger farmers became tenant farmers themselves. None of them ever owned their farmland - they were all tenants. I would say the vast majority of people were if they lived outside of a city.
Home ownership was a post second world war idea that came with rebuilding the state and socialism. giving families something to own themselves. But this wasn't really sustainable as the population grew. Also, I believe that succesive governments becoming less social and more about the individual have encouraged people to cash in on those assets like home ownership. So instead of a son taking over the family home, he was expected to move out young and get his own. Also, job opportunities and education meant more people going into higher ed. So they were not earning and couldn't buy their own home.
Now this generation are therefore suffering from the lack of affordable housing that the boomers are either still living in to use as capital for their old age care or have sold on to each other at increasing prices or have let out their homes.
So the home ownership was the unusual circumstance post war and now we are back to creating a society of tenants. The answer is to secure more tenants rights including longer leases.
I do think that encouraging more people to go to uni has been driven by financial greed of those who lend money to those who go. It began looking that way when I was a student - the banks offered all sorts of incentives to get you to bank with them and borrow money.
