Some may (haven't seen it really here), but I haven't. I have however suggested quite a few requirements for immigrants to be granted citizenship. Prospective immigrants satisfying those requirements would certainly be a net contribution to this country. You even said yes, they were reasonable. You have failed to explain how the fact that the majority of immigrants flooding across the border right now contradicts your belief that we should open the floodgates (which they already are - so your demand is a silly one any way).
