I'm not going to do your research for you, but I'll do you the favour and provide this: https://www.cbc.ca/news/business/real-estate-investment-firms-financialization-housing-1.6538087
We've gone through a very long time at very low interest rates. This means that investors who would normally buy bonds for safekeeping have no choice but to put their money elsewhere. For example, stocks and Real estate.
Due to the free money that we had before interest rates started to rise, stocks were at an all time high but it's not based on fundamentals and higher earnings, so P/E ratios have gotten worse. And there has yet to be a big market correction (that is coming). This makes value investors nervous, but again, there's nowhere else to put the money that gets a good return.
So what would you do if you can't buy treasury bonds and the market is a big bubble? Real estate. Also, the real assets is good to offset any bad bets a corp made in the casino we call a stock market.
So yeah... corporations. All you have to do is follow the money. It's always the same old story. Raw greed and political corruption.
Great message that will likely fall on deaf ears.
Worth a watch though.
