I live in the United States, and here we have plenty of space and resources to go around. I know Europe is a little more crowded, but at least here in the U.S. we have absolutely no reason to complain. If you want less people to emigrate to Europe, I suggest you support tackling climate change head on, and abandoning the imperialist economic policies practiced by the IMF and World Bank, as those are, and will, be the primary reasons why so many people want to escape their home countries.
