Wrong, wrong, wrong, oh-so-terribly wrong.
Hoover put more fingers into more economic orifices than anyone other than FDR. Hoover was a notorious meddler in the economy. Here’s Silent Cal’s own appraisal of Hoover:
“That man has offered me unsolicited advice every day for six years, all of it bad.”
Coolidge also called Hoover “Wonder Boy.”
Most people don’t know it, and Republicans are loathe to admit it, but Hoover was the brainiac behind quite a lot of agricultural subsidies in attempts to prop up grain prices going into late ‘29 and early ‘30. Coolidge, on the other hand, vetoed the McNary-Haugen bills *twice*... and Hoover started down the road of propping up ag commodity prices before FDR arrived.
So he had that going for him.
