Agree with all of this, a small amount of migration and their assimilation into UK society has been going on for centuries and has never been a big problem. I think their food and cultures have added a lot to this country.
I'm not a racist as there only two types of people to me, those I get on with, and those that I don't. I have met good and bad in many different communities.
Mass migration first started in the 1950's and this has led to the creation of gettos and major crime and social problems.
The mega mass migration under the 13 years of the last Labour is causing major problems with crime and assimilation and fighting between groups from different countries that traditionally hate each other. Friends of mine in ethnic communities have also hated this mass migration as it has created major problems in their communities!
Governments that like mass migration love all of these problems as whole new empires of Public Servants can be created, social workers, minority outreach workers, translators, more police, court officials, prison and probation officers and all of the layers of management that goes with it... which with their heavy unionization means they get more political and union donations, to strengthen their political party, so they are more likely to get elected. (This is a positive feedback loop, which is why all Labour administrations in history have ALWAYS run out of public money).
I look at multiculturalism, if it was applied to all of the countries in the world, it would make all societies bland and the same, a bit like modern shopping centres full of multiples all selling the same product lines at the same prices!
You go into any pub and start to talk to people and they all moan about mass migration, along the lines in this forum, so I think most people, don't like what has happened.
The only good thing I can see from this mass migration is that it has boosted the number of working people to pensioners, so the aging of the population in this country will cause less problems, but this could have also been solved, by housing being more affordable and the tax system more sympathetic to the creation of families.
