Krugman's worthless graph on austerity

He attempts to show a linear relationship between 'fiscal tightness' and GDP growth in Europe. But he has Portugal, Ireland andGfeece as the only economies proving the linear relationship.  All the important economies are bunched up and showno effect.

The problem is that once Krugman put's up crappy stats, all the uneducated commenters do not look carefully, and they just take Paul's word without checking the data.
