I've been party to *tons* of economics discussions over recent weeks, and this really isn't a thing.
With few exceptions (yes, there are a handful), there's enormous respect for epi within economics.
I'll concede we're not uniformly strong on soft skills. As a result we're often perceived to be more confrontational than we intend.
The "open the economy" argument isn't coming from econs or epis, but from (mainly) bankers and billionaires (and a few libertarians).
Economics isn't about supporting business, or "the economy." It's about maximizing human flourishing. Understanding self-interest is part of that, as is understanding that self-interest can lead people to do enormous harm to others.
