I will give you an answer which you don't like. It's mostly government regulation and zoning laws that restrict the supply of housing therefore driving up the costs.
You have to understand Mega Corps and Capitalism existed in the 20th century swell, but we have never observed the housing market in shambles the way it is today (Besides exceptional cases like the Great Depression).
It was only after stringent regulations and quality controls did the competition got wiped out and cheap housing like commie blocks are nearly impossible to construct besides when done by the government itself in "The projects".
So really its the Jewish government which aims to benefit their rich Jewish friends.
