Supply/Demand imbalance raises rents. Rent control is one contributor.

Rent control is more than an economic issue, it's a class and moral issue. Why should only people with the means to buy property have the ability to live a stable life? Imagine if your child had to change schools every year because your one of the overwhelming number of people who cannot absorb rent increases.

I personally have zero or negative sympathy for landlords charging usurious rents while simultaneously crying proverty and getting all puffy about property rights. If you can't handle the regulatory environment, nobody put a gun to your head and made you a real estate speculator.
