### Comment:
I'm saying one worker could be worth 20x as much as the other in terms of production and if you don't have that case by case breakdown you can't just uniformly apply population growth to GDP growth like they are somehow in a 1 to 1 relationship.

### REPLY:
The headline productivity number that is cited here and generally used is defined as gdp output per hour of labor. It is pretty much 1:1 related.
