The culture of banking, law, medicine, academia and management come from an era when the people in those professions didn't have to work for a living and, as I said above, were working out of service to the world.
This is why interviews occur during the day, advanced education is required, and advancement is based on acquired social ability rather than technical talent, among other things. It's also why the 40-hour workweek does not exist in such professions. If you're working out of service to society, and not for wages, it follows naturally that you'd continue working until finished regardless of the clock.
Of course, this "working out of service to society" aspect is an utter fiction in many professions today-- especially banking and law. It's just a job for them, and why should it be anything more?
