I was taught Maslow as part of my management training. It is very practical and current to this day. It really helps you set priorities both in the business world and in life.
See, that's my point. It's psychology for dummies, or perhaps worse, psychology not as self-understanding or as mental health, but as manipulation.
I had a my own hierarchy when I taught at the university, the hierarchy of students. On the top of the pyramid were the ROTC people. Day in and day out, year after year, they were the most motivated, dedicated and serious students as a group. I could never talk over their heads. They always had something to contribute to the discussion, and when they didn't understand something, they stopped me and made me explain it. If I had nothing but ROTC students, I'd still teach. They were followed by the people in science and engineering (though getting the engineers to read anything was like pulling teeth, getting them to really write was harder, but when I would have them do something like, design a mill, they were awesome.) Liberal arts majors were so-so, either really good, or killing time for 4 years trying to get laid and drinking a lot. The elementary school teachers, well, not the brightest people ever. But they were always ever so willing to please, they really tried, I'll give them that. Pleasantly dumb as one of my major professors once described them. But the B-School people. They are what has made college suck. And now that they are a majority in so many colleges and universities, college life and university life in general, but specifically academically, has gone downhill. A whole lot of the sickness of our current society, focused as it is on the "What's in it for me" notion that lies at the heart of American Business, stems from these people being in charge. No surprise Bush had an MBA is it?
Look at what happened to our financial system. I could have predicted it, and I almost knew it was coming because I knew the people I was turning out to run it. Self-serving to the total exclusion of anyone and everyone else, immediate gratification at the expense of long range planning, dealing and manipulation, focused only on the next quarter (because why bother after that, I'm going to do so well that quarter that I'll be promoted and those problems I created will be for the next chump to solve) they pretty much ran that ship straight into the ground, knowing full well what they were doing. But hey, they got their bonus, who cares about the rest?
In truth, if a student was lying to me, it was a B-School type. The ROTC people, never in my experience. No weak pathetic excuses, no story so convoluted that it had to come from Rube Goldberg, nope, they were straight-up six o'clock. I usually cut the ROTC types a break because at least they were not wasting my time by lying to me. They took the blame, it was never the fault of someone or something else. If the paper was late, its the ROTC people who would tell me that they just didn't get it done (though in truth most of them were smart enough to plan ahead and see ahead and just came in a few days before and got an extension) and not that world somehow conspired to prevent them from getting it done. (Even though I swore I saw them at the bar on Friday night.)
Now, like clergy in another post thread, there are many fine business people in the US and I'm not saying that's all of them. But B-School's have seemed to attract weasels like iron filings to a magnet.
And they use this, not as Maslow intended, as a self-help tool to assist people in discovering themselves and being all they could be and all that, but as a way to motivate people to do things they really don't want to do. Remember, you never need to motivate people who want to do something in the first place. It tends to be used more to threaten people with level 1 & 2, then to help them achieve 3, 4 & 5.
