Rubio Aide Discusses HBD

Marco Rubio was made to defend his stance on H1B workers. The article mentioned a comment made by a Rubio aide in 2013:

In 2013 when the New Yorker’s Ryan Lizza asked why Rubio’s plan contained such large-scale guest worker provisions, a Rubio aide expressed more bluntly what Rubio implied during the CNBC debate.

The Rubio aide said:“One of the problems you have with this, ‘Oh there’s American workers who are unemployed.’ There are American workers who, for lack of a better term, can’t cut it. There shouldn’t be a presumption that every American worker is a star performer. There are people who just can’t get it, can’t do it, don’t want to do it. And so you can’t obviously discuss that publicly because–.”

At which point another Rubio aide jumped in asserting, “But the same is true for the high-skilled worker.” [my underlines]

By saying that there are American workers who "can't cut it". He's not saying anything incorrect. Here's the thing though, since it is true that not all workers are equally skilled or equally intelligent, it means that as lower skilled jobs are removed from the pool of jobs, those persons who "can't do it" will be unemployable. This has implications not only for the current immigration debate, it has huge implications for the increasing automation of jobs. Since human diversity in intelligence will not be going away, what is the government going to do with the increasing number of unemployable people? If you cannot educate them (since clearly not all have the intellectual capacity to do the advanced jobs) any candidate talking about "new job training" is not addressing the problem.
