So one guy sold 1 mil of stock, the stock dropped 6%, so he avoided a 60k loss. Let's say he expected a 20% drop, and he saved 200k. If a were a millionaire, I wouldn't risk prison for 200k. Even the litigation to avoid prison could cost 100k. And this is the kind of thing you know all angles will be looked into (it took a news agency a few hours to unearth this). If he did it (insider trading), he is very stupid.
This is part of the reason why you aren't a millionaire. Wealth selects for people who do some strange things to make a little extra money here and there... and there... and there... and there....
It's also why people who aren't like these millionaires (whether of similar means but less wealth or of greater means but fewer questionable choices) think some millionaires make foolish, cruel, or inhumane decisions.
