If MBAs really aren't taught "bad management skills," what is it that corrupts them and causes the disastrous short term thinking epidemic in companies these days?
It's not that the MBA training is negative, it's just not enough to be useful on day 1. So the process goes like this:
The guy who hires him is looking to fill a role, and he knows it's not going to happen without a learning curve, so he can never find an exact match to the job.
So you can hire someone who wants twice what you want to pay and doesn't have the exact skillset you need, or you can hire someone out of college who wants 60% of what you're willing to pay and, after some on-the-job training will have the skillset you need. So you take the cheaper one.
And it turns out he's an idiot. But by the time you find that out he's been working there for a year, and he's not so bad that you need him fired right now, and bringing someone else up to speed is going to take a year, so you make do. And 10 years later you realize you're still just "making do", so you put out an ad and replace him.
Rinse / repeat.
