Sometimes neocons remind me of "Christian Socialism" (except that ta good number seem to be Jews) as originally championed by Pope Pius IX. IOW, "give the people everything they want, but keep them from going revolutionary ... or communist.

Frankly, in my opinion, the most common trait, is a completely unsupportable acceptance of the idea that people are far more plastic than they are. Thus, those who have a utilitarian rather than a moral perspective on human societies, are sold the idea that Government should control the social environment--including the economic--in order to remake people in a collectivist/egalitarian direction.
With a hopelessly flawed premise coupled with an abandonment of the moral (as opposed to the utilitarian view of a human society), these movements are alike in being incapable of achieving anything both lasting & worthwhile.
