I think it should be more proportionate, but not solely, we do want to allow people from low pop countries too.

That said, there is a funny thing, some countries consider emigration brain drain, while others consider it a source of income (remittances). I think we, being as selfish as the countries who selfishly rely on remittances, should prefer the highly skilled emigrants who will impact our economy more than emigrants who as immigrants can only offer low skilled labor (currently overrepresented in underemployment figures) this would put price pressure on the lower rungs, increase wages and afford low skills labor livable jobs. The professional class can absorb some wage stagnation whereas low skills blue collar workers have had stagnating wages for too long.
