Yes, the economic law of supply and demand is still in effect. Still, where there is a demand, and it is technologically and economically feasible, someone will usually create the supply.
I think there would be a demand for inexpensive dormitory type housing without the control by the university, military, or other concentrators of population. It is possible that land nearby has become so valuable that rents need to be high to pay for it, but I believe that zoning ordinances have driven up housing costs considerably.
I’ve heard stories back to the 1940s about collusion between lessors in college towns to block new construction, and often to arrange kickbacks from the universities for placements. And the universities, for their part, wanting to force students to live in dorms.
It’s all about the money. On the plus side, at least back then, returning veterans refused to play ball with a lot of the rackets, and they were not men to be taken lightly.
