In our time, the economics profession has undergone tremendous change for the better, and those neoclassical nostrums have been subjected to intense scrutiny by a new generation of economists who have seen with their own two eyes that markets do not always self-correct (another neoclassical assertion) and that sometimes, government intervention is required to achieve good ends.

Republican politicians didn’t get the memo. ** Nor did the American electorate. ** So it’s very easy to tell people, for example, that you’re going to open up federal lands to more drilling, and there’ll be more oil, and prices will go down. That’s about as much economics as your average person remembers from high school, and it makes intuitive sense.

That’s your actual root cause right there.
