As the top Keynesian gadfly, Paul Krugman's recent attack on Margaret Thatcher wasn't very surprising.
In a blog post on the very day she passed, he questioned whether or not Margaret Thatcher had actually made any difference to the performance of the British economy.
Since she had spent much of her career fighting the theories of like-minded economists you can easily understand why Krugman was so quick to take a swing.
But as someone who was actually there, I can tell you the evidence of Thatcher's success is incontrovertible-no matter what Paul Krugman wants you to believe.
What's more, the larger truth is that Thatcher's principles still hold lessons for us today.
