Which is why rent control doesn't address the root causes of the housing problems, and in fact only makes things worse in the long run. It's just virtue signaling without regard to the results.

Rent control = less profit for building properties = less supply.

Lets be clear, the reason there is less supply is not rent control.

It's regulations and NYMBYs that prevents any new building with higher occupancy.

Regulations and NIMBYs increase development costs.

Rent control reduces development revenue.

They both play a part in making building development less attractive, just from different sides.
