As some of the siblings point out, it seems like a contradiction that he complains about the lack of tech workers but also is against mass immigration. These aren't actually opposing when you look deeper - the US does not provide much of a means of legal immigration for high skilled worker. On the other hand, the US also does not restrict illegal immigration so much - it's easy to get a menial job, a driver's license, just about everything without a legal visa status. In essence, you have a defacto second class citizen type immigration with a very limited first class immigration ability of the US. Probably this is the opposite of what would benefit the country most.
