The Covid-19 market turmoil set off a chain of flashbacks in my mind, from crisis to crisis over the past 40 years. They all fit together in a picture of Wall Street fraud and criminal policies, with the virus as the last straw. Last week, I spoke with a young stock trader currently working on Wall Street. I remember saying: “The last time I remember seeing volatility like this in markets, my 40-year Wall Street career flashed in front of my eyes. I was like a deer in the headlights.”
