Incorrect. The leeches are not interested in working for a wage, and few ever enter the work force. The people the aide refers to are the chronically underemployed, former tradesmen and laborers who have been cut out of the workforce by illegal immigrant labor. They are largely uneducated and unskilled so they cannot "retool" as white-collar laborers. But they cannot compete for their old jobs because they cannot afford to live on third-world wages. In the eyes of Marco Rubio they are "not cut out for the work force."
You got it. This is about wage depression, nothing else.
