The human condition produces three types of individuals: the Givers, the Takers and the Fence Sitters. The human condition also produces, with extremely rare exceptions, one over-riding motivation for all that people do: self-interest. Self-interest, despite our best intentions, is usually dominated by two emotions: greed and fear. The best system for keeping a society healthy, wealthy and wise is one which pushes the Fence Sitters in to the Givers camp, by promoting a sense of self-interest that greatly mitigates the emotions of greed and fear. By any reasonable measure, progressivism, in any of its various incarnations, isn't that system.
