Norman is one to talk about lacking qualifications, he’s a political scientist, not an economist. He has no idea what the hell he’s talking about. If he did, he might have had a better math background to study economics, rather than poli-sci.
Really, it takes less math than common sense to understand economics.
Read Sowell’s works - not much math, at all, in those works, and they make infinitely more sense than anything the “experts” are saying.
