I'm not really disagreeing with you, at least in the sense that I do agree that market economies create wealth and wealth is a necessary pre-requisite for funding research. What I think I'm getting at is that I disagree with the common trope that market competition creates fundamental innovation. I think market competition makes companies slaves to the bottom line, fighting tooth and nail in the dirt just to survive. To the extent that the market creates innovation, it does so in companies well-insulated from market competition (monopolies, oligopolies, etc). The decline of Hewlett Packard is a great example. When they became just another hardware company, competing on price in printers, PC's, etc, they ceased to be innovative.
