The Wall Street Journal earlier this week:
We've never obsessed over the budget deficit, because the true cost of government is the amount it spends, not the amount it borrows. Milton Friedman used to say that the nation would be far better off with a budget half the current size but with larger deficits. Mr. Obama and his allies in Congress have done the opposite: They have increased the budget by 50% and financed the spending with IOUs.
Our concern is that the Administration and Congress view this debt as a way to force a permanently higher tax base for decades to come. The liberal grand strategy is to use their accidentally large majorities this year to pass new entitlements that start small but will explode in future years. U.S. creditors will then demand higher taxes—taking income taxes back to their pre-Reagan rates and adding a value-added tax too. This would expand federal spending as a share of GDP to as much as 30% from the pre-crisis 20%.
