You have to consider the time value of money. 19K invested in stock market in 1978 would be over 1 million dollars today, maybe 2 million if you include the taxes paid since purchase.
So put the money in the stock market like everyone else with a 401K and stop constantly whining about getting someone else to pay off your mortgage. It’s not like what the world needs more of is real estate speculation.
I dont think that you can view housing as a fixed quantity of resources that are being allocated.
Houses dont grow on trees. They take many thousands of man-hours to build, and hundreds of thousands in materials, even in the absence of land scarcity.
Landlords front the cost of these things. without them, most of the housing stock would never be built, and there would be nowhere to stay for anyone who doesnt have good credit and a pile of money.
Landlords by and large do not build houses. They buy up existing stock and coordinate with other landlords to constrain supply and raise rents. I dunno who you think is going to believe these fairy tales, but they’re transparently false to anyone with like an 8th grade reading level:
