Classical liberals, libertarians, and conservatives generally argue that welfare and other tax-funded services reduce incentives to work, exacerbate the free-rider problem, and intensify poverty. On the other hand, socialists generally criticize welfare reform because it usually minimizes the public safety net and strengthens the capitalist economic system. Welfare reform is constantly debated because of the varying opinions on the government's determined balance of providing guaranteed welfare benefits and promoting self-sufficiency.
