fair point, that slipped my mind. FDR kinda gets a pass on his deficit, though, we sorta needed to win world war ii.
FDR's deficits began well before the war and they were implemented to stimulate the economy - the same rationale that has been used to explain away every deficit ever since.
U.S. Federal Deficits, Presidents, and Congress
actually, i seem to have conceded too soon on FDR's deficits. he spent massively on the new deal and the war, but of course, he had a lot more flexibility to raise taxes. we no longer have that option, the republicans have ruled it out. so it turns out FDR's deficits were nowhere near as big as reagan's and those presidents who came after.
after the war FDR's deficits were partially paid back in the post-war boom. problem is, wars rarely end in economic booms. usually they bankrupt the nation financing them. but we were fortunate enough to have a massive industrial base post-war (it helps to win; it also helps to not be bombed) and a nice, juicy, ravaged europe to rebuild that gave us a great export market. people think the war fixed the depression but not really, it was the exports to postwar europe and japan. if you look at the graph, the debt was pretty stable after the war, ticked up in the korean war, ticked up again in the vietnam war, steadily climbs and then explodes under reagan, where we spent the USSR into bankruptcy but at the cost that we now have high, structural deficits as far as the eye can see. i think people keep expecting these wars (vietnam, korea, the cold war, iraq, afghanistan) to create a boom the way world war ii, but they don't because they haven't created an export market for us the way wwii did. so we just keep getting more and more wars, and more and more deficits.
