there is some point (idk exactly) where refugees change the culture of the country that adopts them, especially if they are not integrating well.
It might sound bad, but technically immigrantion brings the best people, and leaves behind the rest. Immigrants tend to be the middle class and better educated from those nations.
Eg ppl in states like IL and CA voting for high taxes & social programs, running their states budgets into the ground then moving to places like Austin & Denver & repeating the cycle.
Often the systems in their nations are broken, or socialist, etc. Those who can get out do so. When given freedom most people can thrive, and population is an asset.
