No, it wasn't a wealth creator. It was extremely inefficient across the macro-scale, but created lots of wealth for a narrow clique: me, and the socialist party within which I operated. I systematically impoverished my own nation so that I could test out interesting economic policies and theories in a play-market. Simultaneously, I secretly ran a vast multinational corporation... which did occasionally use public funds to kill competition, eheh, but only occasionally, and very quietly.
