Having read the main saga's books and watched the respective films, I was really surprised when watching Fantastic Beasts and Where to Find Them because of the lack of 'regular jobs' wizards have.
While in the main saga plenty of wizards work in the Ministry of Magic, most have other jobs such as wand dealer (Ollivander), Gringotts employee, dragon hunter (Bill Weasley), tabloid reporter (Rita Skeeter) or even professional Quidditch player (Viktor Krum)...
However, in this film everyone seems to work for the MACUSA, and nobody seems to work in a non-governmental workplace. Is there an explanation for this? I guess it's just a lack of complexity in the film, where the producers chose not to develop a 'vast' world in which non Harry Potter fans could get confused with references to the main saga; but I would like to know if there's a formal reason for it.
