"The war got as high as 129 percent in 1946, which is the current all-time record."

Debt may have been higher than that at the end of the Civil War. By the 1870's you had railroad "Robber Barons" and an economic boom.

How did the economy do likewise after WW2?

“How did the economy do likewise after WW2?”

Truman cut government spending by 50 percent in 1947, and the ratio returned to normal by the 50s.

Do you expect Obama to do the same thing Truman did? I don’t.
