Taking the well-being of abstract concepts like a country over the well-being of concrete individuals is a slippery road towards a particularly unappealing version of collectivism. Me emigrating from Eastern to Western Europe was among the best decisions I have made in my entire life, and I couldn't care less if the outcome of this is my country doing "worse". My country by itself doesn't feel nor think anything, but I certainly do. One of these thoughts is me not believing that I have a civic duty to be less well-off materially and mentally just so my taxes get re-routed to a country I accidentally happened to be born in. I vote with my feet.
