Have you ever taken a college econ course? How about an upper level econ class?
To say your comment is ridiculous is the easiest thing I’ve done in a while. My undergrad econ program had a very substantial math backing. If you don’t want to call that science, fine, but you’ll be hard pressed to call it much else.
You can’t take what idiots like Paul Krugman say and think the whole discipline is corrupt or unscientific. Econ is second to Physics as the undergrad for most law school students. That’s not a holy grail standard by any means but it does mean it isn’t a worthwhile major.
Yes, I've taken the whole undergraduate range - from econometrics to advanced macroeconomics. An econ degree now includes a lot of leftist-ideology courses like "economics of labor" and "economics of environmentalism."
The fact that people can create models using calculus does NOT mean its a science. It means they can create fantasy models - kind of like climate change. Its an interesting intellectual exercise, and certainly not for the masses, which probably contributes to economists' pretensions they are capable of predicting anything beyond the most general of events.
