The welfare system that was formerly called Aid to Families with Dependent Children (AFDC) was retitled Temporary Assistance for Needy Families (TANF). The change wasn't merely semantic; the plan was to make welfare temporary, helping families to give up dependency on government. Before 1996, there was nothing temporary about welfare. It was a permanent subsidy for a lifestyle that subsidized illegitimacy and avoidance of responsibility for individual behavior. Contrary to claims of those who opposed the new system, the dramatic success of the Republican welfare reform was due not to giving more flexibility to state governments, but was due to putting tough restrictions on how the states spent the money.
Now President Obama has ended welfare reform by the gimmick of issuing waivers to the law's "work" requirement. The welfare reform law forbids that, making the "work requirement "mandatory." The TANF law states that waivers cannot be issued unless they are specifically listed in Section 1115, and welfare's "work" requirement" is not so listed. But Obama did it anyway, and that's why people are correct in saying that President Obama violated the law.
