What good is it to become rich if you and your descendants die biologically in doing so?

Watching a Wall Street guru this morning promoting the immigration of high tech people from India or China reminded me of how Wall Street thinkers (along with the left) are killing the golden goose of free enterprise, which has given Americans the highest standard of living in human history. The global Wall Street libertarians have allowed and promoted open border immigration (which the global left also pushes for different reasons) because they believe that free enterprise and money-making are at the origin of human social behavior. While being a great thing, free enterprise is not at the origin of human social behavior, biology is.

When a population of Hispanics, Latinos, South Asians, Indians, Chinese, or Africans immigrate to America they mainly consume their same ethnic foods and speak their same ethnic languages (but usually learn English too) and they keep their same ethnic culture, and for the most part they assimilate only on superficial levels, which is only natural because human nature prefers and selects kin and ethnic group. And so Euro-America slowly or quickly changes to the culture of the immigrants, depending on the speed and number of immigrants and the gradual inter-ethnic breeding that inevitably takes place, and these things change the gene pool which changes the culture, because people create cultures more than cultures create people.

That is why economic nationalism and tariffs, which president Trump has had the courage to promote, makes sense on the biological level, but not to the global Wall Street libertarians who think only of individual money-making liberty.  We need to retain the great free enterprise system but it needs to be moderated by concern for the biological origin of our social behavior; what good is it to become rich if you and your descendants die biologically in doing so?
