Well, "We want less traffic, build more roads" actually helps, in a way: all the additional people driving are doing so because it's more convenient than the next available option, so they're all getting real value out of the extra roads. They just don't reduce traffic as much as we'd expect. And sure, the plan results in more people driving, which is mostly a bad thing due to emissions, so it's not a great strategy, especially when alternatives like mass transit are available to invest in. Housing is not the same. Besides the fact that it doesn't share the qualities that make traffic highly susceptible to induced demand (you've gotta sleep somewhere, whereas you can choose not to drive, or at least choose when to drive), even if the end result of building more housing is that prices stay the same, it's still a better situation. The externalities of "people sleeping indoors" are not nearly as bad as "people driving cars", there would be more people living where they want to live, less of them would have to travel to get to work, environmental impact is lower per person when they live at higher density, economic output is greater at higher density, etc. I get that macroeconomics is not always simple, but that doesn't mean it's always counterintuitive. And let's be honest here: in the Bay Area we've been adding housing much slower than we've been adding jobs for many decades now, and the "over simplistic" econ 101 prediction that prices would go up as a result has been extremely accurate. One point for Occam's Razor. Activists are implicitly making the argument "yeah, our counterintuitive 'build less to reduce prices' policy hasn't worked in the past, but that's only because we haven't been allowed to implement it fully and prevent any market rate housing from being built!", which is the same kind of bullshit all-or-nothing argument that hardcore anti-government types make when we point out situations where deregulation fails to produce great results. Sometimes we just need to accept that maybe there's nothing subtle going on, apply F = ma, and see if the simple solution works. Especially when we've already been trying the crazy out-of-the-box solution and it's been failing miserably. |
