Do you recall the budget deficits when Reagan was obligated to play swap politics in order to get the things which were really important to him?
Reagan is one of the greatest leaders this country ever produced, but you are grossly mischaracterizing how he accomplished it. There were a number of trades which he made in order to focus on those policies most important to him.
This one. Do a google search on Alan Greenspan Ayn Rand and see what you come up with.
