You mean they saved what they could from the Crazy Clown Casino on Wall Street?
the New Deal was awesome. Guy, you clearly don't know people like my grandparents and parents who lived through that, thought FDR was a great man.
Again, no one is naming things after Coolidge...
Crazy Casino? We had not one, but transformational technologies occurring during the 20's: mass production and electrification. Is that what you mean by Crazy casino? All those railroad, energy, and manufacturing companies going gangbusters? Maybe there was 5-10% froth in the DOW, but there was real genuine economic activity behind most of it
But those things had nothing to do with Calvin Coolidge.
What I mean by crazy Casino is what happened in 1929 is the same thing that happened in 2008- stocks were overvalued and the stock market was unregulated, and a lot of wealth disappeared down sinkholes.
Because Coolidge was one of these guys who thinks we can trust the wealthy.
Herbert Hoover, although an awful administrator, had this observation-
"The problem with Capitalism is Capitalists. They're too damned greedy!"
Now, there was a buildup of the middle class that started with Teddy Roosevelt and continued to grow under Woodrow Wilson.
But what really was the game changer leading up to the 1920's was that after WWI, the US went from being an importer to an exporter of manufactured goods. Part of that because we ramped up manufacturing to meet needs for World War I (first supplying the allies and then ourselves) and partially because the Russian Revolution ended Russia's position as the top grain exporter.
(Again, your boy the Tsar exported Russia's wheat to Europe while Russian Peasents starved.... and you wonder why the Commies shot his ass.)
