BTW I was actually looking for specific instances of scams carefully plotted by known people, companies or even countries instead of broad answers like religion.
Lesson for next time, use the text part of your post to define what you are asking or are interested in hearing. Otherwise you get everyone giving glib answers that suck like the above.
BTW, I’m reading Smartest Guys In The Room, the book about Enron, you might be interested in looking up that company. They used very complex financial instruments to deceive shareholders and Wall Street and boost their stock price. Bunch of assholes, some of the shit they pulled was obscene.
