Paul Krugman, the New York Times’s most strident columnist, has a laughably typical headline on his column today: “Keynes was Right.” Krugman once again insists that government spending, qua government spending, makes the country richer.

The best counterpoint to Krugman this week comes not from a free-market economist, but from Andrew Bacevich writing in the Atlantic, about the Military-Industrial Complex and its self-serving argument that government expenditure on arms boosts the economy.
