Nice bit of shade.
The interests of its native people (including giving to those among them that need it some welfare money) is the reason a state exists.
So what sense does it make to compare in per-capita or absolute terms, the welfare given to each group? Any non-zero amount wont be an argument in favor of immigration.
States existed before modern democracy, and the nation-state as we know it evolved from European kingdoms and aristocracies. States exist today for a convoluted variety of historical reasons; certainly not exclusively "the interests of its native people"
