I realize that, even with my very limited knowledge of the work of both Arrow and Sen. My point really was that Sen builds partly on social choice theory and that theory seems not to have produced very acceptable results, given the choices the USA has made and the way those choices seem to be made. In fact, it seems to have little bearing on the actual process. If it did the results might be better. I don't know.
