I have no personal frame of reference for this opinion, but I imagine being a drug runner for the Mexican cartel (or any cartel) is loads more fun in a video game setting than in real life. The latter pays more I’m sure, but the stress, risk to life and limb, and persistent threat of jail time have me convinced to stick with legal employment.
