A market wage can only be set if there is equal negotiating possible between employee and employer. In the case of a power asymmetry, it is up to the government to bring the power back into balance. Granted the reason for the power imbalance is government interference with the free market to begin with, immigration laws give the employer power over the employee that would be absent without the fear of deportation.
