I actually don't know the answer to that last question. We are the wealthiest nation ever. unemployment is at all time lows. Most of these immigrants will do work most USA born people won't even consider doing. IMO, if we wanted to, we could probably take them all in......but that would require some really rich people to give up some money, and for comfortable urban/suburbanites to allow them to live close to them, and other things.....but yes, I think we could feed, clothe, and employ all of them. Probably. Not without some sacrifice, of course. And no, I'm not saying to let them live in our homes...... My guess is that the real answer is very complicated, and requires great commitment of time, money, people, and other resources.....so no, I'm not sure it is realistic that we can take them all in, not in the current world we live in.
