At the same time - in Michael Lewis’ “Panic” they interview a former employee and he says that at the time he was with the Quantum fund, they had over $20b of AUM, mostly family money - over time you’d need a pretty spectacular track record to accomplish that.
I can find a story on the internet about three guys who won $100m in the Powerball, too. Doesn’t mean that the average Joe who buys a ticket will do it.
The book itself is an easy read. It’s the message the author is trying to convey that eludes people i think. You really have to experience it to appreciate the book.
