These "immigrants" were colonizers. They had no intention of assimilating into the native Indian cultures. Most insisted that the Indians assimilate into their British Christian culture or move west. There is a vast difference between subsequent immigration to America and settler/colonization movements. The words "migrant" and "migration" are used as convenient weasel words to obfuscate the central issue involved.
Fischer illustrates that British settler leaders in the 17th and 18th centuries well understood the distinctions between different types of immigration. Their explicit intention was to plant the "seed" of British culture in a new land. They came to make North America British in culture, norms and politics.
Fischer provides two telling quotes as chapter epigrams to make his point. Here's is William Penn's explanation of his purpose for settling the land that still bears his name (but, for how much longer?):
Colonies then are the Seeds of Nations, begun and nourished by the care of wise and populous Countries; as conceiving them best for the increase of Humane Stock. William Penn, 1681Needless to say, this process is now ongoing in Western Europe and the southwest of the USA. The "populous" countries encouraging the "migration" are not wise, but they are brutal. From the perspective of the "mother countries," the purpose of "migration" is for the expansion of their political power and increased revenue (often to the determent of the colony).
Nearly a hundred years later Samuel Johnson commented on the issue even more explicitly:
Whole neighborhoods formed parties for removal; so that departure from their native country is no longer exile. He that goes thus accompanied...sits down in a better climate, surrounded by his kindred and his friends: they carry with them their language, their opinions, their popular songs, and hereditary merriment; they change nothing but the place of their abode. Samuel Johnson, 1773It is no accident that Johnson's quote can be easily applied to the current Mexican invasion of the United States. It is the whole point for the West's traitorous elites support for so-called chain migration. Such policy slows down or ends assimilation as the settlers form enclaves in the host nation.
Any objective observer - much less self-defined intellectual - should understand the differences between legitimate immigration and settler colonization. Instead, they create an inexcusable package deal in which the former requires the latter. Sadly, today this dishonest package deal is being most vociferously promulgated by the libertarian-left and the "Objectivists" running the misnamed Ayn Rand Institute. Don't be fooled by these dishonest poseurs. The national self-interest of the United States or European nations is not their concern.
Whatever their economic rationalizations, the destruction of the West is what they support. This is what they champion as legitimate immigration:
