Maybe America’s “economy” was a lot stronger back then.
1918 was the end of WWII and America was going to enter the “Roaring Twenties”.

Today, we apparently can’t have prosperity unless Uyghur slaves are doing our production under a totalitarian, anti-religious government.
We had a severe but short recession in 1958
