Mankiw's 10 Principles

I came across a short article the other day - Mankiw’s 10 Principles of Economics. A good 2-minute introduction to Economics, and possibly also a good clarity regenerator for those whose brains become clogged and confused like myself. I’m not sure how much point 7 aligns with my current libertarian politics - perhaps the point he makes is true, yet morally irrelevant? Still, worth a look.
