Krugman trapped in box of own making

Paul Krugman's columns in the NYT are becoming increasingly defensive and untenable.  While on some alternate days he make some good political points, his economic commentary is going off the tracks, seriously.  Today's column was among the worst.
"critics who argue that its(the Feds) easy money policies are having damaging side effects,  say increasing the risk of bubbles.  But I hope that's not the case..."  Thanks for the hope Paul.

This column must be read to be believed.  He blames all unemployment issues on policy mistakes, and somehow has no knowledge of the major structural issues that have occurred in our economy, led by technological changes that lead to the need for far fewer workers. 

There is a lot to be done that could help with the unemployment dilemma, and none of it is being done by our current inept Congress.  No viable answers will be found in Krugman's rigid and inflexible opinions.  His unbudging approach makes him seem like the Arthur Laffer of the left.
