Nope, absolutely not. The problem is that they have a feedback system which is attempting to maintain a constant value. This could be a driver pressing the gas, a thermostat (as listed below), or the Fed trying to modify interest rates to achieve a result. The problem is, if you do everything right, and there's no economic collapse, people wonder why you need to exist. If there is, you're clearly useless. I fall into this a lot, but I really hate the attitude of engineers and scientists believing that everything can be solved by approaching a problem a certain way. We have this idealized, fetishized approach that if you define all your axioms and have a rigid framework in place, you can solve anything. Of course, as soon as you try it in real life, especially in a field like sociology or economics (which, of course, we deride as not being scientific enough), it all goes to hell. I would recommend that anyone who is of this opinion - that economics, psychology, linguistics, et al are not scientific enough - actually take a course in that area. What you find are: people who are experts in a field are really smart, yes, they have thought of that already, no, it didn't work. It's a very humbling experience.
