My thoughts on why it will happen.
Video got cut off, so will continue in a future segment
The link above shows the latest number for the population in america.
The link above shows the labor force participation rate
Common sense says if population is going up, more people will be participating in the labor force.
UNLESS the jobs that they need are sent to other countries via free trade agreements.
And the jobs that they need are importing non-immigrant guest workers to take the jobs that they need.
