So, what happens, is that we take the human side out of it. That is fine. In Buddhist philosophy, there is a human side and a 'pure' side. But the situation is different with "economics." We are already putting ourselves into a category, a subject field, called that. When you call it "economics," the saber is taking its first cut (Or: the word "economics" is the first stroke of rhetoric), and it's a humanistic cut.
Economics is fundamentally human;
What they are doing is applying numbers to it.
