As a Libertarian/Humanitarian who believes in open borders, I fundamentally disagree. The 'brain drain' argument ignores how skilled migrants create international networks that benefit their home countries through investment, knowledge transfer, and trade links. The data is clear: immigration increases innovation and economic growth in both origin and destination countries.

The real issue isn't immigration vs. domestic welfare - it's ensuring fair policy for everyone. Free movement of people, like free trade, creates more opportunities than it removes. Restricting human mobility causes measurable economic damage through reduced innovation and productivity, while harming international cooperation and solving none of the problems it claims to address.
