With regards to work and wealth, there wasn't much commentary that was made through the movie. This course section was never mentioned in director and cast member interviews either. It can be argued that cryptocurrency, a digital form of currency that is not reliant on a central bank or nation to assign it value, was utilized in the movie and therefore makes a statement about it.
While cryptocurrency is utilized by Charon in order to maintain anonymity during their transactions, the movie uses it as a cheap way to capitalize on the relatively unknown nature of cryptocurrency, and simply does so in order to play up the "mysterious" and "evil" nature of Charon.
