Who immigrates into Finland? Is it ethnic Finns from other countries, or middle eastern/african refugees, or economic migrants from eastern europe, or what? It doesn't seem like a place with a lot of immigration.

This also seems like a strong argument for Australian/Canadian skill points immigration. I don't think there would be a problem with 50mm immigrants who were one sigma smarter/richer/etc. than the current US population, provided they had to spend 3-7 years of residency before citizenship/voting, and ideally if there were some way to spread them out over time or geography to avoid overloading local services (which have funding which lags population growth). Maybe give the states a say in how many immigrant visas they will sponsor, on top of a federal pool. I can imagine Michigan would love to have a lot of high-skill entrepreneurial immigrants move in.
