It will change when people want it to change, just like workers' rights did over the last century.

If you don't want to pay a million quid for a house in London, refuse the game. Move elsewhere. Find a different way to get by in life, perhaps even a different country.

People won't do that, though. It's more likely, IMO, that the entire world becomes more feudalist again until there are few escape hatches.

But it'll ultimately be because people keep buying in. As long as people, en masse, continue to max bid housing (whether for rent or to buy) this situation will continue.
