First Paul Ryan wants to end...

...Medicare and now he doubles down on Rick Perry's assertion that Social Security is a Ponzi scheme. From Chris Cillizza's blog:

On Laura Ingraham’s radio show today, Rep. Paul Ryan (R-Wis.) agreed with Texas Gov. Rick Perry (R) that Social Security resembles a Ponzi scheme. “It’s not a criminal enterprise, but it is a pay as you go system where earlier investors, or say taxpayers, get a positive rate of return and the most recent investors, or taxpayers, get a negative rate of return,” said Ryan. “That’s how those schemes work.”

Did he say "scheme?" Are these people serious?

Every other developed nation in the world provides a safety net for its most vulnerable citizens. Now, suddenly, the world's largest economy -- ever -- can't do the same?
