When its welfare rewrite became a political issue, HHS then invented a new standard that appears nowhere in its original memorandum and says that 20% more people need to move to work from welfare than before to get a waiver.
And while you may be inclined to believe that people should work even if it means earning less than if they allow the government to pay for them in the guise of welfare, it becomes difficult for individuals to live up to that standard when the ability to feed their children hangs in the balance.
Conservatives will always attack expansions of the welfare state as intolerable constraints on freedom, and eventually accept them as standard parts of the political landscape.
