This is an old pattern. Newcomers arrive, start businesses, and are treated with resentment by the older residents. In the past, there was always a “racial” element. This time, there isn’t one, but it’s the same old pattern.
I have worked with a lot of people who have come from African countries, like Nigeria, or South Africa. Every one of them I’ve meet has been very nice, and very professional, and very appreciative of this country.
They think the blacks in this country are idiots, for not appreciating what they were born into.
