Of course, this result doesn't mean the spill will prove a net positive for the economy. Lowrey sensibly comments that "five years from now, there won't be anymore clean-up workers ... [b]ut ... the fishing industry and the tourism industry will still be suffering." Klein makes a broader point:
This is a nice object lesson in the inadequacy of GDP as a measurement of societal well-being. I could blow up the biggest building in every city in the country and the resulting reconstruction effort could mean a big temporary increase in GDP. But blowing up buildings is not a sustainable way to grow your economy.
