For reference, Bloomberg terminal costs $24,000 per year.

Before the 1928 crash and subsequent regulation as well as going off the gold standard, instituting the Fed, and other things, the ups and downs were insane in both socks and inflation.

Consider the DJIA here from 1919 to 1929: https://www.macrotrends.net/1319/dow-jones-100-year-historic...

See inflation here for 1920 to 1929: https://inflationdata.com/articles/inflation-consumer-price-...

See the massive fluctuations in inflation as well as the DJIA? After the New Deal and other reforms, we not only hit post WWII American growth but a relatively stable upward trend in the markets and policy with targets like stable economic growth and more recently stable inflation (currently I think a 2% target).

Regulation and restrictions plus Fed oversight has granted our modern economy relatively stable year over year growth and inflation. Stability means future predictions become ore accurate, economic panics/recessions can be not necessarily predicted but solutions approached strategically.

Deregulation and instability can make people insanely rich similar to the hyper leveraging of this whole RH thing but one usually has to either be the know like via have insider information or be prepared to tank everything for their own arrogance like when some guys tried to corner the gold market in 1869 (Black Friday) or the onion market in the 1950's: https://en.wikipedia.org/wiki/Cornering_the_market

This page where I pulled inlfation data is really neat. I'd recommend checking each decade with recessions: https://inflationdata.com/Inflation/Inflation_Rate/Historica...
