The only real way to fight this is oversupply imho. Can't financialize something that doesn't generate outsized returns. If expected returns are lower (and risk higher) than the next financial class, money will move to that other financial class instead. Right now, real estate is low risk/high reward compared to the next best option (stocks?). So...money pours into real estate. Increase that supply to the point where finding a renter is at least marginally challenging, and you'll find that cash goes elsewhere.
