earn her bachelor's degree while supported by welfare. Vanessa D. Johnson, a professor at Northeastern University, asserts that the implementation of PRWORA cut access for single mothers, namely African American single mothers, to attaining a higher education for themselves. By creating time limits that force them into working without finishing a degree, Johnson says African American single mothers are left unable to better themselves through education. With education having such a strong correlation to higher wages, she considers it crucial that welfare policies allow for mothers to attend college in order to lift themselves out of poverty. Another criticism placed on PRWORA by some scholars is that its transition to work provisions negatively affect the ability of low-income mothers enrolled in the program to find a job. Single mothers enrolled in TANF tend to have lower rates of literacy, and therefore finding employment that within the time frame of the "workfare" component becomes more difficult, or leads to underemployment. Welfare-to-work programs have also been criticized for only offering training for low-wage work. An education-first approach has been proposed as an alternative that could provide welfare recipients with more options for employment. Although the incentivization of financial independence is a goal for both recipients and providers, many TANF enrollees feel disincentivized from finding paid work due to low pay and the instability of this transition. Varying rates of success Critics of the law argue that poverty in America increased from 1979 onward after Reagan's presidential campaign criticized deficit spending and that the temporary large reduction in the number of people collecting welfare was largely a result of steady and strong economic growth in the years following enactment of the law. Political scientist Joe Soss questions the definition of success, asking whether "success", as measured by caseload reduction, was merely a political construction for policy makers to easily claim credit in front of their constituencies. In analyzing the effects of welfare reform, he notes that caseload reduction is not very demanding, especially compared to improving material conditions in poor communities:The TANF program does not offer benefits sufficient to lift recipients out of poverty, and despite a strong economy, the majority of families who have moved off the TANF rolls have remained in poverty. Considerations of another traditional economic goal, reduction of inequality, only makes matters worse. Welfare reform has coincided with massive growth in income and wealth disparities; it has done little
