I don't understand, can you explain?

Increased automation definitely decreases the per capita need for working-class people.

We would probably have a lot more automation already (especially in low-end agriculture/service-industry) if not for a seemingly inexhaustible supply of cheap labor from south of the border.

Just noting it doesn't matter how our 'native' population grows or shrinks - we'll have about the same available labor supply per capita. In fact as we push education, our labor supply shrinks as the next generation aspires to more than lawn maintenance.
