While technically not a pyramid scheme, there are painters, and their managers (“interns”), both of which are made up of solely undergrad college students. The former is responsible for most of the physical work, while the latter is generally responsible for dealing with the business end of things and finding home owners to shell out exorbitant amounts of money for inexperienced work. Above the bottom two rungs we find the permanent management at the company. There may be several levels to this as well, I never interacted with anyone from the actual company while working there, and makes me very suspect as to what they’re really doing.
