The character of totalitarian systems is at all times an emphasis on control, primarily the control and manipulation of the individual. Communism, fascism, and Islamism are all willing (and, at times, even eager) to delay or ignore economic advancement and scientific progress if either would compromise control or diminish power. In fact, it is often the mission of totalitarians to vanquish economic and scientific progress if at possible since they both interfere with or systematically undermine control.
