Unions Support Minimum Wage Laws, Because

Unions support minimum wage laws, because

A) union workers are typically paid the minimum wage.
B) an increase in the minimum wage paid to low-skilled labor increases the opportunity cost of employing high-skilled union labor and, hence, increases the demand for union labor.
C) an increase in the minimum wage paid to low-skilled labor increases the opportunity cost of employing low-skilled labor and, hence, increases the demand for union labor.
D) an increase in the minimum wage paid to low-skilled labor causes the supply curve of low-skilled labor to shift leftward and, hence, increases the demand for union labor.
