The key point is "at those wages". The overall assumption in the economy is that it's good and proper for low-skilled jobs to be very low paying, despite otherwise being very unattractive. As long as people are unwilling to pay the proper cost for hard labor, they'll keep hitting this problem of local people not willing to do the work for a pittance. Then, when they circumvent the local workers, they'll be surprised that local workers are discontent.
I do agree with that. The same as with the trope about McDonalds, etc. being "starter jobs" for teenagers, etc., and that's why it's okay for them to not pay a liveable wage, etc., which has no origin in fact (re the minimum wage law) and only in Republican ideology.
