I could count on one hand, with fingers left over, the number of "managers" I've met in the last couple of decades who had undergraduate degrees in any business related field.
Following up on your point, people who fancy themselves "managers" don't make themselves thus qualified by regurgitating Mis-used Buzz-words and Acronyms, whether from a two-day seminar or from a premium MBA diploma mill.
Eventually, the market does have a correcting effect on companies that promote mis-management, because effective competition does eventually arise and eat their lunch, unless the mis-managed firms lobby and maintain enough political force to stifle competition.
If you have a degree in management, then why do you know know the difference between management and managers? Most people that work in management are not managers: they perform a management function (marketing, finance, accounting, strategic planning...).
If you have a degree in management, then why don't you know that not even a management expert can judge a manager's decision without seeing the data and options open to the manager at the time when that decision was made? Have you done a single case, in any of the subjects towards your degree?
Finally, I never said that you "know nothing about management:" how on earth can I possibly know what you know (although I can tell from the posts some things that you don't know)? What I said was that you cannot learn management by observing managers. Why do you confuse the two? Following up on your point, people who fancy themselves "managers" don't make themselves thus qualified by regurgitating Mis-used Buzz-words and Acronyms, whether from a two-day seminar or from a premium MBA diploma mill. By the "premium MBA diploma mill" do you mean places like the Harvard Business School, Wharton, the Graduate School of Business at Chicago? Have you been anywhere close to those places? Worked with any of those people? What a pathetic remark: smearing a group of people without any justification whatever does not make you look smart; on the contrary, you are screaming once again that you have no clue of what you are talking about.
Eventually, the market does have a correcting effect on companies that promote mis-management,
I don't know where your "management degree" is from, but in an average school you would fail an introductory course. Where on earth did you see a company that promotes mis-management? To get a degree in that area one must use the word "promotion" a thousand times (in marketing, strategic management, possibly accounting). You have no clue what the word means and what constitutes managerial decision-making.
I have no idea even how we got to this nonsense. You put words in my mouth and then went on to argue against them. Thank you, but you don't need me for this discussion: you are arguing against a straw man (and manage to be losing that argument by saying complete nonsense).
