In terms of career paths, the ones belonging to the FBI and judges don't come across as very attractive in "Wolf of Wall Street." On the other hand, the guys and girls who learn to sell, even if it's near-worthless penny stock, seem hot.
One is that work can be fun. Before things get out of hand, Jordan et al. have a hell of a lot of fun at not being Boy Scouts and Girl Scouts. Unlike the earnest FBI and judges, they enjoy having a quick eye for finding how to get from Point A (no money) to Point B (plenty of money) in a way that doesn't require too much heavy lifting. Law students and lawyers watching their moves might drop some of their own plodding mindset and behavior.
Another key lesson is that the ability to sell is everything. It might be a point of view or a stock. Jordan regains his influence, power and easy action in federal prison because he is a trained salesperson. After release he has a whole new career path as an international sales trainer.
The third lesson is never to give up. After he lost his first Wall Street job during the Crash of 1987, Jordan found an even better fit for himself in a boiler room hawking penny stocks. When the feds tied the noose around his neck, he knew it was time to rat. That got him three years instead of 20. In the slammer he figured out the angles.
Those offended by "Wolf of Wall Street" should grow up. There are fun, easy ways to make a good living and hold onto hope. That I see as the film's message.
