"Stockman's disillusionment didn't take long. While his compatriots were eager to cut taxes, he found that they were unwilling to shrink the government, that special interests were able to beat back any cuts he proposed, and that supply-side economics wasn't as effective as he'd hoped. These concerns spilled out in a
lengthy December 1981 Atlantic cover story, written by William Greider, in which Stockman provided a tick-tock of his efforts since taking office, which ended with exploding deficits and an economy veering toward recession.
Autumn was cruel to David Stockman's idea of how the world should work. The summer, when furious legislative trading was under way, had tattered his moral vision of government. Politics, in the dirty sense, had prevailed. Now he was confronted with more serious possibilities--the failure of the economic strategy and the political unraveling that he had feared from the beginning. On Capitol Hill, where Stockman was admired and envied for his nimble mind, where even critics conceded that his presence in the Cabinet was essential to Ronald Reagan's opening victories, politicians of both parties were beginning to reach a different conclusion about him. Despite the wizardry, Stockman did not have all the answers, after all. The wizard was prepared to agree ....
Stockman's prospects for balancing the budget were getting worse, not better. The optimistic economic forecast made in January to improve his original budget projections came back to haunt him in September. The inflation rate was down considerably (a prediction fortuitously correct because of oil and grain prices) but interest rates were not: the cost of federal borrowing and debt payments went still higher.
Where did things go wrong? Stockman kept asking and answering the right questions. The more he considered it, the more he moved away from the radical vision of reformer, away from the wishful thinking of supply-side economics, and toward the "old-time religion" of conservative economic thinking."
