So we give up with a half-measure, that helps the rich moreso than the poor without addressing the underlying issue?

This isn’t a helpful or sustainable approach. Should we give up on climate change because reducing carbon output is hard, or say, “Well, as long as you don’t use coal, its good enough.” Of course not. Not to mention that making immigration and/or citizenship more accessible isn’t an impossible task at all, esspecially relative to climate change or weath inequality.
