Another piece in the puzzle:

One of the themes that came up while I was profiling White House manufacturing czar Ron Bloom earlier this fall was managerial talent. A lot of people talk about reviving the domestic manufacturing sector, which has shed almost one-third of its manpower over the last eight years. But some of the people I spoke to asked a slightly different question: Even if you could reclaim a chunk of those blue-collar jobs, would you have the managers you need to supervise them?

It’s not obvious that you would. Since 1965, the percentage of graduates of highly-ranked business schools who go into consulting and financial services has doubled, from about one-third to about two-thirds. And while some of these consultants and financiers end up in the manufacturing sector, in some respects that’s the problem. Harvard business professor Rakesh Khurana, with whom I discussed these questions at length, observes that most of GM’s top executives in recent decades hailed from a finance rather than an operations background. (Outgoing GM CEO Fritz Henderson and his failed predecessor, Rick Wagoner, both worked their way up from the company’s vaunted Treasurer’s office.) But these executives were frequently numb to the sorts of innovations that enable high-quality production at low cost. As Khurana quips, “That’s how you end up with GM rather than Toyota.” […]

After World War II, large corporations went on acquisition binges and turned themselves into massive conglomerates. In their landmark Harvard Business Review article from 1980, “Managing Our Way to Economic Decline,” Robert Hayes and William Abernathy pointed out that the conglomerate structure forced managers to think of their firms as a collection of financial assets, where the goal was to allocate capital efficiently, rather than as makers of specific products, where the goal was to maximize quality and long-term* market share.
