Roughly a decade ago, I spent a year in a developing country working on a project to promote human rights. We had a rotating team of about a dozen (mostly) brilliant local employees, all college-educated, working alongside us. We invested a lot of time and money into training these employees, with the expectation that they (as members of the college-educated elite) would help lead human rights reform in the country long after our project disbanded. I got nostalgic and looked up my old colleagues recently. Every single one is living in the West now. A few are still somewhat involved in human rights, but most are notably under-employed (a lawyer washing dishes in a restaurant in Virginia, for example).
I'm torn on this. I'm sure my former colleagues are happier on an individual level. Their human rights are certainly better respected in the West, and the salaries are better. But the potential good that they could have done in their home country is (probably) substantially higher. On my way out, I signed letters of recommendation for each employee, which I later found out were used to pad visa applications. (I am perhaps feeling a bit of guilt over contributing to a developing country's "brain drain" as a result.) After I left, there was a blowup between two of the Western employees over whether to continue supporting emigration. The TL;DR of the disagreement was "It's the nice thing to do, and refusing to support emigration could reduce morale and our ability to hire go-getters" versus "We can't have lasting impact if our ringers keep leaving."
I'm curious about what other EAs have seen in their orgs. Is there any kind of organizational policy that exists on matters like this?
This seems pretty unlikely to me tbh, people are just less productive in the developing world than the developed world, and its much easier to do stuff--including do good--when you have functioning institutions, surrounded by competent people, connections & support structures, etc etc.
That's not to say sending people to the developed world is bad. Note that you can get lots of the benefits of living in a developed country by simply having the right to live in a developed country, or having your support structure or legal system or credentials based in a developed country.
Of course, its much easier to just allow everyone in a developing country to just move to a developed country, but assuming the hyper rationalist bot exists with an open boarders constraint, it seems incredibly obvious to me that what you say would not happen.
