Most MBAs have no frigging concept of the real world out there and think they're important thanks to their MBA, whereas the rest of us have more important things to worry about. Firefighters have a grasp on perspective. MBAs clearly do not. With more and more people doing MBAs that says a lot about the future!
Yeah I can see how say a Harvard or Wharton MBA obtained in the 80s or 90s was super valuable these days they're a bit hit and miss I think.
If someone is already on track for a good career they can perhaps be useful. I used to work with some older guys who were continually bitching about a colleague in our US office and how they couldn't believe how he'd been promoted etc.. he'd not too long beforehand been a regular manager (and before that a developer just like them) but had since become an MD and then a CTO (he'd done an MBA in his spare time). After a merger he got another C level appointment and looking at linked in he's had another C level move and then a further move to become a CEO of a reasonably large (as in worth over a billion) company. I suspect, for him, his MBA was useful For others it's perhaps been a waste of money, I remember one IT/trade support guy in a Canadian bank used to have MBA, CFA in his e-mail signature and you'd just feel sorry for him!
I suspect that a lot of MBA types are very aspirational and perhaps have big egos etc.. and so for them the car is sort of a status symbol, for someone to just get the same type on a whim shortly after is perhaps seen as diminishing it for them or something?
