The trick with economics is to realize that 99% of all discussion is about a particular flavor of economics. It's almost always about theory and implementation, not principles and abstractions. Inevitably, there is also a significant political aspect that is often (but not always!) overlooked.

Even if there is a "raw" theory of economics that describes the "what" in a universally agreeable way it'll never tell us the "why" and "how" of it, let alone how politics should (or should not) be intertwined with the issues.
