Consider what happens when a business engages in ruthless cost-cutting. From the point of view of the firm’s owners (though not its workers), the more costs that are cut, the better. Any dollars taken off the cost side of the balance sheet are added to the bottom line.
But the story is very different when a government slashes spending in the face of a depressed economy. Look at Greece, Spain, and Ireland, all of which have adopted harsh austerity policies. In each case, unemployment soared, because cuts in government spending mainly hit domestic producers. And, in each case, the reduction in budget deficits was much less than expected, because tax receipts fell as output and employment collapsed.
Now, to be fair, being a career politician isn’t necessarily a better preparation for managing economic policy than being a businessman. But Mr. Romney is the one claiming that his career makes him especially suited for the presidency. Did I mention that the last businessman to live in the White House was a guy named Herbert Hoover? (Unless you count former President George W. Bush.)
