Despite sweeping welfare reforms in the 1990s and generally healthy economic growth in recent years, domestic poverty remains intractable. Moreover, signs are emerging that so-called deep poverty is growing sharply — most significantly among children. U.S. poverty is fueled by a long list of problems, including Katrina's devastation, immigration, the growing income gap between rich and poor, the subprime mortgage fallout and education disparities. Conservatives say solutions must emphasize personal responsibility, higher marriage rates and fewer out-of-wedlock births. Liberals focus on the negative effects of government budget cuts for anti-poverty programs, tax cuts benefiting the wealthy and the need for more early-childhood-development programs. The Democratic Congress is making poverty a priority issue, as are some of the presidential candidates. President Bush himself acknowledged the gap between rich and poor, raising hopes that a bipartisan effort would be found to reduce poverty.
