I had a post with this title back in October ’11, on the L.A. smog of past decades and in which I asked how libertarians would have dealt with it in the absence of state regulation and environmental legislation. I never got any kind of response, needless to say—not from a free-marketeer, at any rate, though one did send an email with a link to an article about how anti-pollution regulations hinder job creation, or something like that, but that in no way addressed my question. Now we’ve been reading about the off-the-scales smog alert in Beijing the other day and comparisons with the infamous London pea soup fog that afflicted that city for well over a century, until the first clear air laws were enacted there in the 1950s. London was hardly the only city with a present-day Beijing-like smog problem, of course. The Atlantic has a piece today on smog in Pittsburgh through the mid 20th century. Incredible to think that people lived with this (as they live with it today in Beijing and elsewhere). Scroll down and click on the link of the photo show of what Pittsburgh looked like at noon.
So I repeat my question to libertarians, and to anti-government Tea Party GOP types more generally: if they had their way and government got out of the business of environmental regulation—and with clean air and other such acts repealed in the interest of an unfettered free market, not to mention abolishing subsidies for mass transit—, what do they think would happen pollution-wise? If there were a return to the smog status quo ante—an inevitability, one would presume—what would they propose doing about it, if anything?
I’m not going to hold my breath waiting for a response.
