I wouldn't go so far as Economics being pseudoscience, it's obviously not as foundational as math or physics, i.e. it builds on top of math and social sciences.
Also you should definitely differ between political/macro economics and business economics.
Former I would certainly put into the science category, and there are a lot of scientists that advocate towards radical changes in politics because of climate change. Latter is certainly debatable and certainly less "sciency"...
Karl Marx and Keynes were also economists... That is a broad scientific/philosphical field we are talking about. But there are many opportunists and demagogues in that field.
I used to work in science in hydrology and did read a lot of papers from macroeconomists (they use similar apporaches). There are defintly serious scientists in macroecomics. Tbf, I have my doubts when it comes to business economics.
The show 'The Rig' has this as a plot device in season 2, going into season 3. Anybody else sad that sci-fi is not out pacing reality by more then a few years anymore?
I wonder how long it'll be before they'll start selling bottled purified air, or something. I could even envision metered filters as a mandatory installation for every enclosed space.
