I am truly mystified by that commonly held view. Ryan has proposed a so-called "plan" that will only work if the following 4 things occur:

1. Unemployment must drop by 2.5% within a year of the enactment of Ryan's "plan."

2. Unemployment must drop to 2.8% by 2020 (an historically low number and about 1/2 what many economists believe is the level we need to avoid inflation).

3. Revenue must dramatically increase despite a reduction in taxes.

4. The housing market needs to boom again, and soon.

There is nothing in the history of the world that suggests that anything remotely like any of those things will happen.

The Heritage Foundation embarrassed itself by supporting Ryan's plan when it came out. When people asked why they were publishing such a ridiculous unemployment projection, they tried to delete the offending figure from their website. Unfortunately for Heritage, Krugman had downloaded their original attempt to bolster Ryan. http://krugman.blogs.nytimes.com/2011/04/06/memory-hole-alert/

So, seriously, how can you say "Good for Ryan"? I don't get it.
