I love your skepticism about 'intellectual hubris'! Business schools can serve a very productive education service when students take the finance/accounting tracks if they don't have those backgrounds. This allows people without those backgrounds to either transition into new careers or get the underlying knowledge they need to take on new responsibilities/roles in their existing careers. A lot of work in both finance and accounting are 'complex' so daily practice require detailed knowledge. Even if they may not be 'sophisticated', (e.g. PhD level mathematics). Some areas, like derivatives, are both complex and sophisticated. Sources: 1. My Mom got an MBA to change fields and then used her learned knowledge in finance+accounting constantly working for a state municipal agency. 2. Our CEO got an MBA to learn the knowledge he needed to move forward in his career/transition into different roles. I agree with the other responses to you question that in some areas of the US (e.g. Silicon Valley, East Coast) a 'name brand' MBAs may be used as a signaling requirement for certain jobs or to advance in a career - more so than for eduction. This gets more silly when a personal already has the necessary skills! And part of the value these schools supply to their graduates a network of similarly interested business contacts. So would the veteran engineer moving into management be helped... perhaps/but probably not. But can a person looking to change fields or areas benefit hugely by doing an MBA? Yes. Absolutely.
