I miss Eisenhower. Under his eight years he understood the WW2 debt must be paid down first and the US needed rest to transition from war production to peace production. Under his admin he kept US out of major wars, kept gov spending including defense to a minimum as our WW2 debt was paid down as the US transition to peacetime manufacturing and consumption. The only major fed program was building our interstate highways which kept many Americans vets employed as industry needed time to transition completely from war to peace and create jobs for the last vestige of demoblilized soldiers who came home from war and occupation duties in Europe, and Japan. it was Eisenhower’s boring admin that paid down the WW2 debt that laid the strong financial foundation for JFK and the 1960’s.
Eisenhower had very little nondefense spending to contend with, although he did expand social security and start the interstate system. As of 1960, defense accounted for more than half the whole federal budget, which was less than 100 billion dollars.
He never had to pay for Medicare or the rest of LBJ's Great Society.
As far as "demobilizing" after WWII, he of course reduced the size of the military but had hundreds of thousands of troops remaining in the former axis powers, segueing directly into the Cold War. Then there was the little matter of the Korean War, before Ike even took office and needed to be "paid for" as well.
The economy under Ike was good but not great, with a serious recession in the mid fifties. When JFK ran in 1960, one of his effective campaign phrases was a promise to "get the country moving again," which he did by passing a major tax cut, which is usually acknowledged to have set off the boom of the "Soaring Sixties."
Circumstances make a difference, like the fact that in 1960, when OPEC was formed, the world price of oil at the well head was still under $2 a barrel. Not a bad thing for revving up an economy based on basic heavy industry and a burgeoning auto industry, but had nothing to do with Ike or his policies.
