Those theories are based mainly on the effect of Cuban immigration in Miami, however they lack a control so you can't really conclude anything.

Besides, yeah, if you hire people who will work for any salary, the amount of jobs will increase, but salaries will decrease, for locals as well. After some time, locals will flee sectors where the migrant workers are brought in, creating further self-inflicted "labor shortages"...requiring more migrants!

The main winners are capital owners, who, thanks to the migrant workers, can now acquire a larger part of the added value generated by workers.
