Interesting essay on migrant crisis

Also there's so much uninhabited space in the USA - many migrants tried to make the trek to the West Coast.
But they met problems too - the American Indians, still trouble festering there.
Same happened in Australia with the Aborigines, and S. Africa.

I should say, the first modern migrants, because the native peoples were migrants too, long ago, as were we all.

He did mention that the first migrants to the US were European.

He didn't mention that the enlightenment ideals on which ththe US based its constitution were formed in Europe, and France in particular.
Britain's Thomas Payne - who was so disliked by the British establishment - helped formulate this in the US
However I will need to re-read the essay to give it more thought before commenting further.
