An Entitlement Reform?

I used to work a lot with Bob Reischauer (former MedPAC vice chair and CBO director) on Medicare stuff, but have not followed it for several years. I'm also out of the loop on most high level tax discussion. But I've come to put a great deal of trust in the insights of the Urban Institute on both issues, so when they are responding positively towards the Medicare plan released by Ryan and Wyden today, I'm inclined to view it favorably. I'm curious if Bob will weigh in on it.
