Earlier quoted context omitted.
It makes perfect economic sense: it's a simple supply and demand curve. Increasing the number of workers decreases their value. The only confounding factor is whether the increase in workers increases the speed at which the economy grows/ I'd guess it probably does, but not enough to offset the downward pressure on wages.
> It makes perfect economic sense: it's a simple supply and demand curve. Increasing the number of workers decreases their value. That assumes that the number of available jobs is perfectly-sized and fixed, and that there's no other work that could be done (or no under-employed, existing work that could be done better) if we had more workers. That would seem not to be true.
No it assumes the exact opposite of a fixed number of jobs-- it assumes the other work wasn't being done because wages were too high to make it profitable, but as the workforce grew the price of labor dropped until employers wanted to hire into those jobs. That's the whole idea behind supply and demand.
