The Fed did a study some time back estimating CPI levels since 1800. [1] They found that from 1800 to 1950 the CPI never shifted more than 25 points from the starting base of 51, so it always stayed within +/- ~50% of that baseline. That's through the Civil War, both World Wars, Spanish Flu, and much more. And obviously the US economy increased in sized quite exponentially from 1800 to 1950, with no persistent inflation whatsoever.

It's even more interesting to contrast this from 1971 onward. 1971 is when Bretton Woods ended and the government was given a free hand to start 'printing money' so to speak, and inflation became the new policy. Since then the CPI has increased by more than 800 points, 1600% more than our baseline. And it's only increasing faster now - to the point that these numbers I'm giving are already rather outdated.

The US economy faced repeated economic catastrophes from 1800-1950 largely because the government was unable to enact monetary policy. The long depression of the 1870s happened pretty much solely because monetary supply contracted and populists got elected to fuck with the silver/gold standard. Causes of the great depression are more varied, but contraction of money supply due is certainly one of the leading ones.

Yes, the economy expanded greatly over this period, but you have to separate inflation from many other causes such as innovation, increasing labor supply, better education, increases in the amount of investment. I think its pretty clear that the economy wouldve fared much better in the 1800-1950 period if the government was partaking in monetary policy that focused on small but positive inflation.
