This is my understanding and observation too. Over the last 25 years or so, notwithstanding the 2008 dip, low interest rates have propped up rising house prices to the point where you were foolish NOT to have a house loan if you could get one. As a result the rich have very much got richer simply by borrowing money and living in a house. Compared to living in a cave I have been paid about £20-25k a year to live in my house over the time I've owned it. This would have paid for a LOT of mortgage. When I was in a rented house I was paying about £6k a year in rent and obviously the asset growth went to the landlord.Every time interest rates and gone low and stayed low, along with the inevitable QE, the wealthy have become wealthier.
We are now seeing a correction fuelled by higher rates - home owners and landlords are seeing higher costs and this is causing house demand and pricing to shrink.
