Good point. Mission should not easily "drift". "Mission drift" in the period you describe is something we can hope will not recur as strongly as it did during the last quarter of the 20th century. During that period, one did not "drift away" when leaving a social mission in order to follow promised profit opportunities. Rather, one connected to the nature of true and efficient existence itself - the Market. This Market and its 'Forces' were given a religious character of transcendental perfection on which the end of history could be based. In a religion of this type, the institutional details of price creation can be ignored except by the people who build and maintain your "code of capital". US satellites like Germany are under strong pressure to conform to the US creed, and the Landesbanken did so. Unless all the lessons of recent collapse are forgotten, it will be hard to create that sort of belief-community-in-greed again soon, so perhaps public missions will be taken seriously for a while.
