Why Dog the M.B.A.?

Seems that every time I read an article about the M.B.A. degree, some author or professor at Stanford/Harvard is mentioning that just about every college and university is teaching for it in the wrong way. Some say too much analysis and not enough clinical experience, others feel that students are too young to be taught business administration, never having administered a business (no real world experience). Yet others seem to think that core subjects such as accounting, economics, marketing, and finance get disproportionate attention at the expense of crucial "soft" skills such as leadership, teamwork, communication and the ability to think outside the box of discipline. Is it time for the MBA degree to be more than just a "sifter" of students for employers? Some schools are taking, what the feel, corrective action by adding courses such as leadership, collaboration and the like. Others are allowing M.B.A students to handle the school's own million dollar investments fund. Is this the appropriate remedy to at least appease the critics?
