The way I think about it is this:
Older generations/baby boomers had higher inflation, but low house prices. Their payments were still in line and easily paid with a single income. They start to get into power and slowly begin dropping rates. House values go up on their almost paid off houses and they use that equity to begin buying more houses for rentals, second homes, whatever. As things go along, there is the housing crash where prices plummit. These same people have a lot of equity and cash and buy up more. This continues for another decade where they continue to drop the interest rates and prices go sky high.
Now they hold a large portion of the available houses creating the artificial shortage and jack interest rates back up which just brings up payments. They still control the supply, so prices come down a little but just not enough. Now they have a larger percentage of the population that can no longer afford or qualify for a home loan, so they just created a ton of renters.
Now they still have all these rentals and positive cash flow, so any deal that shows up even with the high interest rate they can still drop cash on.
All the people that were pissed at the world in the 60s and 70s when they were becoming adults saw how the game was being rigged, and they are just getting their piece of the pie with 0 regards toward the younger generations.
