How about this: If below minimum wage illegal work wasn't a good deal for guest workers, there wouldn't be illegal immigration to the US.
This doesn't mean its not exploitation, although not every H1B is being exploited.
> The workers being exploited by wage depression here are the American ones
85K new H1B's a year aren't enough to depress wages when the population of the US is 300M+. Especially when there is record demand across industries. Look at tech, every company wants to hire more and is competing with high salaries.
> and that's not even addressing the infrastructure costs of a growing population which is distributed evenly instead of being born solely by those incurring the cost.
I don't understand this point. Isn't every citizen benefiting from the improved, expanded infrastructure? Legal immigrants like H1Bs pay the same taxes as any citizen or a permanent resident.
