The most viable societies are national socialist. This is true whether such a society has a government called National Socialist or whether its government is a monarchy, a democracy, or any other form.
In fact, any true culture is national socialist.
National socialism, as the term is used here, involves the following:
First, national, indicating a nation. A nation is a group in which those making up the group hold a pronounced sense of commonality and sameness with others in the group. This sense of commonality and sameness – this identity – is based upon similarity in physical appearance, attitudes, beliefs, likes/dislikes, and language; with resultant similarities in behaviors, responses, clothes, music, and architecture; along with the same group history. The feelings of commonality and sameness lead to a relatively high degree of fondness on the part of those within the group for others within the group and for the group as a whole.
Next, socialist, indicating cooperation. Due to the relatively high degree of fondness that those of a nation feel for others of their nation and for their group overall, they hold a pronounced degree of altruism for other individuals of their nation and for their nation as a whole. Thus, there exists a pronounced willingness – in fact, a pronounced desire – to cooperate.
Formal National Socialism overtly recognizes and encourages processes that occur naturally in cultures. So, this form of government is likely more consistent with human nature than is any other form.
