"Government accounting is different from that in the private sector. A firm that borrows to make a good investment will see its balance sheet improved, and its leaders will be applauded. But in the public sector there is no balance sheet, and as a result, too many of us focus too narrowly on the deficit. In reality, wise government investments yield returns far higher than the interest rate the government pays on its debt; in the long run, investments help reduce deficits. To cut them is penny-wise but pound-foolish, as New Orleans' levees and Minneapolis' bridge attest."
