Well, it's not the worst article I've read. Some decent ideas I guess. I think rent control in its current form is fundamentally a misguided and bad policy that strongly encourages some people to consume vastly more housing than they would in a market clearing situation --- I'm talking about middle or high-income people who will never let go of the rent controlled apartment they've been in for 10+ years.
I think if you really want to subsidize housing for people who can't afford market rates, you should give them money for housing. End rent control, let the market sort it out, and hand people money. Rent control looks like it's "free" because you're not writing checks to the poor, but you force the landlord to pay, which discourages people from becoming landlords in the first place.
