I generally agree, but this doesn't work in countries that restrict cross border movement of their own citizens.
North Korea neither gains talent from abroad nor loses talent to other countries. Europe loses talent to the United States. It's a flawed comparison, but North Korea is not a better place to work and do business than Europe, which this comparison would imply.
> North Korea neither gains talent from abroad nor loses talent to other countries.
It does. Nobody defects to North Korea, but there are thousands of North Korean refugees in the west. That should tell us something. Same thing for Cuba. Their inflow to outflow ratio is 0 (nobody wants in).
> Europe loses talent to the United States.
Net loss, but looking at the ratio it's still > 0 (some people move from the US to EU, just less than the other way around). So something like 1/4 (one person moving into the EU for 4 moving to the US).
if I wanted to rule without opposition I might take steps to drive away or suppress the intelligentsia, so I'm not sure what your metric is really measuring, maybe effectiveness of my tyranny?
