From the article: "In the early 1960s, a pair of Nobel Prize–winning economists, Paul Samuelson and Robert Solow, argued that in order to keep unemployment around 3 percent, U.S. policy makers should be willing to accept that "the price index might have to rise by as much as 4 to 5 percent a year. That much price rise would seem to be the necessary cost of high employment." Both economists were close to Kennedy, who pushed for low interest rates, hoping to spur rapid economic growth."
This idea turned out to be false.

This turned out to be true. And, lastly:
"In the 1970s, that is exactly what happened in the American economy, often by design. As Frum wrote, "The United States had consciously chosen to inflate its currency. It made that choice because of the political ideology and personal weakness of the men entrusted with the job of managing the American economy: their utopianism, their arrogance, and then finally their cowardice." The inflation that vaulted Reagan into office was not an accident or an incidental effect of policy. It was the result of deliberate policy choices."
