An interesting article about Jean-Baptiste Say by Amadeus Gabriel:
Thus, society could work without government management if people carried out their business and let other people carry out their business at the same time. Say underlines his position by giving some historical examples. Writing in 1819, he observes that at times during the previous thirty years, France had found itself in a situation in which all the authorities were suddenly halted. In these critical moments, no government was at all existent. And what does Say observe? During these periods, the essential functions of the social body could not have been carried out in a better way: everything worked, better than would have normally been the case. Say states that the worst occurred in times when people were too much governed.
