No, the wage is low for occupations with poor working conditions because the supply of unskilled workers is high relative to the demand for them.
Step-by-step explanation:
A compensatory difference also known as a compensatory differential or an equal difference is defined as the additional amount of income to be offered to a specific employee in order to motivate them to accept a certain undesirable job compared to other jobs that the employee might perform.
When unqualified workers ' supplies are high compared with their production, their wages are low. In that case it is the disproportionate supply of low-wage workers who are compromised by the principle of compensating salary differentials.
