Compare two policy strategies for ensuring that no families fail below the poverty level. One is a transfer strategy, which leaves the determination of wage rates entirely up to labor supply and demand, and then uses a negative income tax or earned income tax credit to ensure that each family's total income is above the poverty line. the other is a living wage strategy, which sets a minimum wage at a level high enough to ensure that a family with two full-time workers and two children earns enough, without transfer payments, to raise family income above the poverty level. what would be the advantages and disadvantages of each strategy?
