I was a personal trainer for one of these guys' wives once. It was shocking to me to see the frivolous spending, 4k a month credit card bills, spoiled rotten kids, wasteful living, etc etc.
It just is not me. As long as what they are doing is legal I have am fine by it, it just does not fit my personality.
Many divorces, many affairs, many prostitutes, much excess.
What did you expect to find in that environment? A "Father Knows Best" lifestyle only slightly expanded with the income of several million a year?
The excesses today are the same as they've always been -- going back to the 1800s. The only thing shocking is that new (and more interesing) vices haven't been created to absorb the greater amounts of money floating around. Though luckily for my viewing pleasure, they've managed to find some new permutations...
Fortune, at least the monetary kind, doesn't particularly favor the virtuous.
