I don't believe that, but today, with so many of us knowing the tricks, and what not they teach in these programs; if I owned a company, my MBA count would be low. The accounting/statistics aspect of these programs is fine, but the cheap sales/staff ploys that these programs teach are just irritating, and very noticeable.
Managing creative people - which may include some software people - is not the same as managing a pool of lawyers or accountants.
Software has a problem because too many managers think all software people are interchangeable development units.
In reality there's a universe of psychological difference between corporate biz-logic devs and the kind of creative lunatics who used to work at PARC - and all shadings between the extremes. Put good people in the wrong environment and they'll be worse than useless.
Same for all the other many possible dimensions.
The MBA is basically capitalism's answer to the Soviet "party apparatchik."
