Social initiatives may be undertaken, based on apparently coherent theoretical propositions, that in practice have significant negative consequences in society. Those committed to such propositions then argue that such consequences will diminish over time. The merit of such arguments may be unclear when the time scales are such as to be a significant proportion of the life times of those disadvantaged by the initiatives.
Governments arrogantly assume that they can control their economies and that they can dictate the value of their currencies. Speculators correctly assume that this is not a sustainable policy. As with the controversy over protectionism, a commitment is made to a plausible theoretical proposition which in practice is shown to penalize employment, working standards and the obvious well-being of the public. Although theory suggests that these difficulties are temporary and that eventually all will benefit to a greater degree than before, it is unclear exactly when such benefits will manifest.
The bigger the theory, the better.
