> I don't see the value in large numbers of unskilled workers entering the US every year. With a potentially large wave of automation coming, the US shouldn't straddled itself with lots of unemployable drivers, farm workers, etc.

Your argument is that the jobs these people do might be automated away so they shouldn't come here. Is that correct?

I would counter that many of these jobs can't easily be automated and that these workers are much more adaptable than you give them credit for. You just aren't going to see robots picking strawberries or hanging sheetrock on a large scale anytime soon for economic and technical reasons. Delivery drivers and dishwashers have very low cpaex vs robots that could do the same. These immigrants also start small companies at higher rates than native born Americans.

I guess I just don't get the rationale for keeping out low skill workers. The pay for goods an services, provide labor, start businesses, and generally do quite well.
