As explained by Fred Foldvary in his article Land Rent as a Tax:

“The old rule in the US housing market was that a household should not pay more than 30% of its income to housing. In the USA, median rent rose by 4% from 2001 to 2012. Some 35% of households spend more than 30% of their income for housing. One fifth spend more than half their income on housing, according to the Joint Center for Housing Studies of Harvard University. Many of the poor in the USA obtain housing subsidies, but then the landlords raise the rental, since the tenant can now afford to pay more.

Some cities respond with rent control, but government cannot control land rent. Government can only control who receives the rent. If the landlord does not obtain the rent, then in effect, the tenant is keeping what would have been paid, and is obtaining an implicit rent. While some tenants benefit from the rental-recipient control, others are locked out of housing.”

Not much else to say here other than that the core solution isn’t to cap how much people can pay for our Earth’s finite land, but to have its value be collected publicly and used to untax the investment and work that makes up the production process, including building houses. We also, of course, need to relax land-use restrictions that harm more than help (e.g. Euclidean Zoning).
