Ryan is not trying to do either of these things. In fact, he's one of the few people trying to make them solvent, so that they don't go bankrupt for future generations.
You see, when you stop imaging people who disagree with your politics as evil inhuman monsters, and actually seek to understand them, your prospects in life become much more brighter, and you will be less constrained by hatred and self-righteousness.
I don't think my opponents are evil inhuman monsters. I do think my opponents have a serious race problem. Is that no longer PC to say?
Also I probably wouldn't mind Ryan's reforms to Medicare as the costs of the program are indeed spiraling.
