Of course they did not; they were DAY LABORERS. And as such, their manual labor did not require a degree or even English-fluency, but it did require skill.
Our current day laborers have a lot of skill, gained through years of experience. They are helping to build this country's needs now and Kelly's ancestors helped construction during their time.
Worse yet, he sees nothing wrong with removing children from their immigrant parents and sending them to 'foster care whatever'. Need I remind you the horrors orphaned, abandoned, and abused children in this country endure? Our foster system fails 99% who enter it. Kelly and his racist ilk are xenophobes who are fighting AGAINST changing laws to address this issue.
