I remember a 20 question interview of Richard Branson years ago (in the Boston Globe).
“How do you become a millionaire?” “Easy. You start with a billion, and buy an airline.” (rim shot)
The Slimes bought the Boston Globe and some other properties for over $1B, and sold the Globe for around $70M after ~20 years.
If the Slimes sold for less, that would be notable in a case study at business school, but not unexpected.
Someone asked Richard Childress (NASCAR team owner) to to make millions in NASCAR. He said the same thing.
