"Get your economy out of the ditch, and borrowing costs will rise [because growth prospects rise]. That means you have to stop wasting money on low-value spending initiatives and make sure your taxes are high enough to cover the bills for the high-value ones. But that's not a "dark side" of economic recovery, that's just what economic recovery is. It's a situation in which private actors want to invest their money in private business undertakings, such that low-value public sector spending is wasteful."
