第15章貧困と経済的不平等

The U.S. government has implemented a number of programs to assist those below the poverty line and those who have incomes just above the poverty line. Such programs are called the safety net, to recognize that they offer some protection for those who find themselves without jobs or income.

From the Great Depression until 1996, the United States’ most visible antipoverty program was Aid to Families with Dependent Children (AFDC), which provided cash payments to mothers with children who were below the poverty line. Many just called this program “welfare.” In 1996, Congress passed and President Bill Clinton signed into law the Personal Responsibility and Work Opportunity Reconciliation Act, more commonly called the “welfare reform act.” The new law replaced AFDC with Temporary Assistance for Needy Families (TANF).

TANF brought several dramatic changes in how welfare operated. Under the old AFDC program, states set the level of welfare benefits that they would pay to people experiencing poverty, and the federal government guaranteed it would chip in some of the money as well. The federal government’s welfare spending would rise or fall depending on the number of people in need, and on how each state set its own welfare contribution.

Under TANF, however, the federal government gives a fixed amount of money to each state. The state can then use the money for almost any program with an antipoverty component: for example, the state might use the money to give funds to families with low income, or to reduce teenage pregnancy, or even to raise the high school graduation rate. However, the federal government imposed two key requirements. First, if states are to keep receiving the TANF grants, they must impose work requirements so that most of those receiving TANF benefits are working (or attending school). Second, no one can receive TANF benefits with federal money for more than a total of five years over their lifetime. The old AFDC program had no such work requirements or time limits.

TANF attempts to avoid the poverty trap by requiring that welfare recipients work and by limiting the length of time they can receive benefits. In its first few years, the program was quite successful. The number of families receiving payments in 1995, the last year of AFDC, was 4.8 million. November 2020, according to the Congressional Research Service, the number of families receiving payments under TANF was 1.0 million—a decline of nearly 80%.

TANF benefits to poor families vary considerably across states. For example, again according to the Congressional Research Service, in July 2020 the highest monthly payment in New Hampshire to a single mother with one child was $862, while in Mississippi the highest monthly payment to that family was $146. In part, these payments reflect differences in states’ cost of living. As reported by the Department of Health and Human Services, in 1995 total spending on TANF was approximately $19 billion. Spending increased yearly through 2001, then it was roughly flat at approximately $26 billion until 2005, then it increased again through 2010, where it peaked at nearly $35 billion. It then decreased again to around $30 billion in 2020. When you take into account the effects of inflation, the decline is even greater. Moreover, there seemed little evidence that families were suffering a reduced standard of living as a result of TANF—although, on the other side, there was not much evidence that families had greatly improved their total levels of income, either.

The earned income tax credit (EITC), first passed in 1975, is a method of assisting the working poor through the tax system. The EITC is one of the largest assistance program for low-income groups, and as of December 2021, about 25 million eligible workers and families received about $60 billion in EITC. For the 2021 tax year, the earned income credit ranges from $1,502 to $6,728 depending on tax-filing status, income, and number of children. The average amount of EITC received nationwide was about $2,411. In 2021, for example, a single parent with two children would have received a tax credit of $5,980 up to a modest income level. The amount of the tax break increases with the amount of income earned, up to a point. The earned income tax credit has often been popular with both economists and the general public because of the way it effectively increases the payment received for work.

What about the danger of the poverty trap that every additional $1 earned will reduce government support payments by close to $1? To minimize this problem, the earned income tax credit is phased out slowly. For example, according to the Tax Policy Center, for a single-parent family with two children in 2013, the credit is not reduced at all (but neither is it increased) as earnings rise from $13,430 to $17,530. Then, for every $1 earned above $17,530, the amount received from the credit is reduced by 21.06 cents, until the credit phases out completely at an income level of $46,227.

Figure 15.5 illustrates that the earned income tax credits, child tax credits, and the TANF program all cost the federal government money—either in direct outlays or in loss of tax revenues. CTC stands for the government tax cuts for the child tax credit.

In recent years, the EITC has become a hugely expensive government program for providing income assistance to people below or near the poverty line, costing about $60 billion in 2021. In that year, the EITC provided benefits to about 25 million families and individuals and, on average, is worth about $2,411 per family (with children), according to the Tax Policy Center. One reason that the TANF law worked as well as it did is that the government greatly expanded EITC in the late 1980s and again in the early 1990s, which increased the returns to work for low-income Americans.
