CNN Money just caught up with 32-year-old Zak Williams, son of the late Robin Williams, who has an MBA from Columbia and who lately has been co-teaching a class Curtis "Wall Street" Carroll, a self-taught inmate investor at San Quentin State Prison. It's an overall "financial literacy" class, and the pair teach it to inmates eager to learn every Thursday.

Williams says that doing this community service at the prison has "been very helpful for me personally" in the wake of his dad's death, and he tells CNN in the clip above how he feels like gaining a better relationship to, and understanding of money can help rehabilitate criminals.

"Whether they're violent or non-violent crimes, a grossly disproportionate amount of them are money-related. Understanding and having a healthy relationship with money is absolute core toward personal success in this life."
