"Chips are a vegetable"

Way back in college, a bloke called Sinclair Davidson was my lecturer for final-year economics. Since then, he’s started writing for the excellent _Catallaxy__ _blog, which is full of interesting stuff: here’s the story behind the Aussie stimulus package; and here’s a wonky but interesting piece on hospitals in Canberra. (He also wrote a great piece for the Institute of Public Affairs on the benefits of migration - worth a read.)

And then I stumble across this:

Nobody wants to eat steak with a sweet potato mash and a jus. Substitute for chips.

How come we never covered this in lectures?
