The answer is always speculation investment. People are on average richer and real estate is the only trully limited economic resource as we have limited land especially in desired locations.
Seriously lookup how much of real estate is uninhabitable.
People are richer, the tech is better and everything we know about economy would indicate that real estate should be more accessible but that’s not the case because the market is manipulated.
The best part? If you invest in a stock index you’ll almost always out do real estate ownership almost anywhere in developed world. So people are hustling this stupid game while they could just sit back and watch money do money things.
Imagine going into an economical agreement with Russia lmao
