We are already well below our replacement birth rate. If people my age have any hope of EVERY retiring, we need a MORE robust immigration system, not to be shutting our doors in the face of the immigrants and refugees that were already seeking to come here. Besides, every one of our white ancestors (for those of us who have European heritage) benefited from being allowed to come here with few or no restrictions (pre-1920s, just get on a boat. Done.). Why do some think that they are so special that THEIR antecedents deserved a better life but that OTHERS, today, do not? I mean...#WTF?
