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.
