How did black, Muslim, Indian, Chinese, Mexican ghettos appear in America, UK, France, Germany etc?

People moving to a different country naturally feel more comfortable living in areas where there are other people with the same culture and language and where they won't experience prejudice. For example in America the Irish chose Boston and Philadelphia and the Germans chose towns in the Dakotas and Wisconsin.

In European countries the Asians, Africans and Afro-Carribeans come from those countries' former colonies. The UK invited Asians and Afro-Carribeans over because of post-WW2 labour shortages.

These ghettos obviously came as a result of immigration. America and Europe allow integration with quotas accepted each year from various nations where poverty and lack of opportunity make people want to find a better life. It's something the Americans and Europeans feel they're obliged to do, to an extent, because of their relatively good economies compared to impoverished countries.

Back in the 80s and before, free movement was very easy. Lots of them came to the west and stayed for many years and then had British born kids. Once your kids British in the eyes of the law you're British too. BTW Muslim isn't a race like Chinese and Indian, it's a religion. Anyone can be Muslim.

It happens because immigrants aren't ready to negotiate on wages, so they get underpaid, they're forced to live in poorer neighborhoods, and with the Project-Development boom of the 50s/60s(because before WW2, things were a lot more mixed, the redevelopment after the war created these naturally formed ghettos) there were less, and less neighborhoods, which concentrated them together.

Poor integration by immigrants. It isn't the giver me ts jib to integrate immigrants, but if they are here for a better life they should try to do more integrating themselves. There are way too many immigrants without education or English so are unemployable, they were invited by labour to shore up the labour vote.

Why should undereducated people be here at all? Time to restrict immigration from those destined to enter as benefit abusers and drains in resources.

Social engineering under both parties since 1948, and all without the consent of the electorate.

Send then back if they won't integrate.....it's their responsibility to integrate not mine!

We had colonies...UK,Portugal,France, Belgium,Netherlands.....Go work it out!
