I think the want tends to become a need (not for every business in every market) because of a few pressures, among which is the competitive pressure for capital. If this business won't deliver growing profits, capital would move into another that would. Without capital, there's no money for procuring the means to do new product. I think that gives the basic pressure for profit maximization that we see around us. It's not universal - non-profits, private firms which don't take outside capital whose owners are opposed to profit maximization, and some others tend to not be subject to it. So for some types of businesses I think it qualifies as need, or else they risk their survival and therefore the usually high compensation of their exec layers. I'm not married to proving it need and not want, just thought you might not have looked at it from this angle.
