Ryan asks, but doesn't answer, right questions
Rep. Paul Ryan's discussion paper on "Expanding Opportunity in America" has much to admire. It puts attention where it belongs - on poverty and upward mobility for those at the bottom of the income distribution. It argues for an expanded earned income tax credit, the best way to reduce poverty in work. And it correctly explains what's wrong with existing federal programs. When it comes to reforming those programs, though, Ryan's proposal leaves a lot of questions unanswered.
