Or worse in the UK where they all went to Oxford and got a PPE.
I like this question. I try to use it on myself. It gets to the core of some of our responses. I.e. we should opine with evidence when we can. But I would suggest one slight change.
> Are any academic or working economists who make these arguments in positions of power?
I'd say yes. E.g. economists working for The Heritage Foundation for example.
I believe working economists are more nuanced and critical than what filters through the medias and politicians. I've been trying to teach myself some economics. For instance, I read Mankiw's "Principles of Economics", a widely-used introductory college textbook and I find it balanced. The author tries to convey different points of view and warns the reader about the limitations of the field.
Actually, I've even found Milton Friedman in "Freedom and Capitalism" to be more critical of capitalism that I'd have expected (e.g. concerning monopolies and externalities, I read it a while ago though).
He's against government-enforced monopolies; market capture is fine by him (because surely an upstarted would disrupt the incumbent & wouldn't be subject to anti-competitive actions that kill their business).
Agree about the politicization of other fields of science too. Maybe it is more of a political problem in econ too.. thats hard :(
It's a bit like why people still publish in Elsevier in spite of them being awful - it's because it's how you get on in your career. Similarly differential equations about spherical cows get you promoted.
"Respectable" is questionable, but the economists that do are invariably motivated by ideology.
Improving Economics as a discipline, making it more evidence driven and predictive, is a good thing. But sadly there will likely always be people who distort and misrepresent its theories in order to fit their own agenda. We see that in pretty much every scientific field, even ones far harder than Economics.
