I'm curious if anyone has seen research or thought about the inverse, Poor to Rich country spillover effects. While the findings in this post are promising, I worry that they may further incentivize under-investment in international development, as I am similarly worried about efforts to increase high-skill immigration to developed countries, which I fear benefits rich countries at the expense of poorer ones. These are just intuitions though, so I'm not sure if these concerns are unfounded.
I'm curious why you think aligning governments with the interests of voters is value-aligning rather than technical. I can see that being the case for autocratic regimes, but isn't that the whole point of representative democracy?
