Krugman:

[T]he new British budget announced on Wednesday and the rhetoric that accompanied the announcement might have come straight from the desk of Andrew Mellon, the Treasury secretary who told President Herbert Hoover to fight the Depression by liquidating the farmers, liquidating the workers, and driving down wages. [. . .] The British government’s plan is bold, say the pundits — and so it is. But it boldly goes in exactly the wrong direction. It would cut government employment by 490,000 workers — the equivalent of almost three million layoffs in the United States — at a time when the private sector is in no position to provide alternative employment. It would slash spending at a time when private demand isn’t at all ready to take up the slack.

[. . .] What happens now? Maybe Britain will get lucky, and something will come along to rescue the economy. But the best guess is that Britain in 2011 will look like Britain in 1931, or the United States in 1937, or Japan in 1997. That is, premature fiscal austerity will lead to a renewed economic slump. As always, those who refuse to learn from the past are doomed to repeat it.
