Imagine a future where it is impossible for the poor classes to purchase a home, because some trillion dollar real-estate funds have captured the entire marked.
Some of these real-estate investment companies own hundreds of thousands of rental units. They purchase swaths of blocks, all over the world, and do nothing but increase the price. Usually they just purchase parts, or entire portfolios off smaller companies.
The goal is monopoly. And it has worked well of the past decades with low/zero interest rate policy.
