The debate among economists over the size of President Joseph R. Biden Jr.’s $1.9 trillion stimulus package has drawn attention to past cases of inflation spurred by big government spending. Both sides have cited the Vietnam War of the 1960s as a precedent of an outbreak of inflation that would be difficult to reverse… A better historical analogy may be the large but temporary surge in inflation in 1951, related to the Korean War, which did not pose any lasting damage to the US economy.
