Well the ideal in the founding of the United States that comes from Biblical principle is one people out of many tribes with the same ideal. It is easy to see which political party has striven for the vision to be fulfilled and which party has always warred against the principle. By the way the Bible is filled with prophecy about the end of tribalism. Not necessarily the end of nation states. But the end of tribalism.

Isaiah 11:1 And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of his roots (that is the messiah) .....6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. 7 And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. 8 And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' den. 9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.

The animals are illustrating different peoples no longer warring against one another. But living in peace together. The child illustrates real Christians. The mountain illustrates the Messiah's invisible kingdom. A kingdom that influences the nations for the better. The snake holes illustrate evil in the world. No use me listing many more of these. It gives you the proper idea of what these prophecies are about.

In “Suicide of the West” Jonah Goldberg references Economist Friedrich Hayek who says “humans are programmed to understand the world in personal and tribal terms.”

However, Goldberg says the development of modernity resulted from learning to hold our tribal instincts in check.

“It’s natural to give preferences to family and friends — members of the tribe,” Goldberg writes. He says seeing strangers as trustworthy individuals with rights and dignity “does not come naturally to us. We have to be taught — carefully taught.”

Controlling tribalism builds cooperative societies. The opposite always leads to “honour” cultures, an obsessive sensitivity to offence, gangs, vigilantes, violence and bloodshed.

I’ll respectfully disagree with your assertion that capitalism leads to corporations that are more powerful than government. By its very nature (monopoly on the use of force, ability to tax, etc) government is vastly more powerful than any corporation within its jurisdiction. And just as hungry to grow. The problem as I see it occurs when corporations (sometimes but not always threatened with regulation) trade something to the government in exchange for favored status. The result is a partnership between government and the corporation, sometimes referred to as cronyism.

Tribalism is a term used to frame the conversation of groups into a negative connotation. Like all of this stuff--or most of it--we talk about, there are good sides and bad sides to things. Nationalist is used as a pejorative, and it's used to describe 'neighborism'. Political correctness is politeness/courtesy, or staunchly oppressive policing of free thinking. Capitalism can be good or it can be bad--so can socialism or communism. Usually better in theory than in practice. Capitalism builds the imperfection of human beings into the system, and that's why I think it's a superior system. The good in socialism and communism is stuck in the fantasy of Utopia, because it ignores the inescapable imperfection in human beings.

Our language is too restricted. We get trapped into recycling terms, but end up confusing communication in the process. I've stopped using the term pair 'right-left' because of this drift. Now, I say left/non-left, as it's actually more proportionally attuned to the division between the terms. We need to introduce new terms into the lexicon. I think we've stretched the ones we have as far as they can go. Aren't there linguists somewhere thinking about this stuff? Have they not noticed the problem?

Any way, there's nothing wrong with tribalism until it's used to marginalize or oppress another group. The tragedy is we lose what's good about tribalism just because we start conflating terms.

Some points to ponder -

• The tribalism of the Japanese caused them to forgo modern development due to their desire of isolationism
• The explosion of human development/progress coincides with capitalism.
• I've always compared capitalism to pure democracy. If you don't like a huge corporation you can choose to stop voting for them.
• Diversity is only a strength when you have a common culture - "Bowling Alone"-Putnam
