From Matt Kahn (who I think is being subtley snarky on progressives):
One person's challenge is another person's opportunity. To rephrase this point, there is demand and supply. As the cold regions of the country have experienced heavy snowfall, this has created jobs for guys to clean it up and opportunities for guys who sell salt. Progressives should view climate change as creating a Keynesian stimulus. The cost and time it takes to clean up from a shock do represent an adaptation cost but these costs will fall over time due to the magic of capitalism. The money that is spent for the clean up goes to somebody and in a time with great concern about the 99% much of this $ will go for paying for basic labor that can't be supplied by someone in China because the work for the cleanup is here.
I would simply mention this as a comment at the Matt's blog, but there is no comment feature there. Here is the Google on broken window fallacy at this blog.
