I will be sharing Prof. Sowell's article with my Microeconomics students. I raised many of these same points in a class discussion last week. However, I don't expect to make much headway on this topic with my wife (also a college professor) who rants about "obscene" oil company profits whenever she fill her car with gas.
See if the MSM carries any stories about oil companies losing money, for the exact same reason they're making lots of it now, if crude prices suddenly drop. And then see if your wife cares.
