What the image mentions was true for a few decades and for a minority of humans only. Home ownership is still at a very high level compared to what it was even 100 years ago. Hell, you should know that if you’re from the UK, people used to live in towns that were developed and owned by the factory owners, that’s how they managed to move people from rural regions to the city so quickly, outside of that, housing in the city was no better than the slums we see all over the world these days.
