I think the benefits of multiculturalism are perhaps experienced more by the middle class.
If you’re middle class, you can afford these exciting new restaurants. There is less competition for your job. You can have a cheap cleaner, a cheap nanny, and you live in a nice neighbourhood so don’t live with the social tensions that some of us do.
100% agree.
We’re in Camden. My DD is shunned and excluded at school as she’s Christian, and most of her classmates aren’t. She sits alone at lunchtime as she’s told that eating lunch with her is like eating with a dog. 
That is so sad. And (some) people wonder why some white people/Christians prefer to live in areas that are predominantly white/have British born people in them.
And as I said much earlier in the thread; ethnic minorities always want to be with their own culture and race, so it's disingenuous to say it's wrong/racist/xenophobic when white people want to be with their own culture and race.

According to the last census about 82% of the UK population identified as white British. Of the greater London population it was about 44%. A huge discrepancy.
I agree that several parts of the UK not just London don't feel English anymore.
My late Grandmother was born and bred in an area in the North of London. Her family had lived in and around the area for 100s of years. But during her lifetime it changed massively and it made her very sad and insecure. A lot of the local shops that she had visited all her life changed hands and no longer catered for her needs. And the area started to look shabby and run down. We went to her GP once and she was the only woman without a face covering. She said that she felt like a stranger in her own home town.
To her multiculturalism and diversity was not a good thing.
This in spades. ^
And THIS ^ kind of thing is the reason that loads of people I know moved out of London - after being born and raised there and living there 4, 5, 6, or 7 decades.
The areas they knew and loved became very run down, and most of the shops no longer catered for their needs, and most of the new shopkeepers didn't speak English so they couldn't make themselves understood. In addition, the schools were so full of ethnic minorities that the UK born/Christian children were being taught all kinds of things irrelevant to them, and that they didn't understand, including various languages that they would never, EVER use.
Problem is (as many posters have said,) multiculturalism is often not a good thing for many UK born citizens, because the ethnic minorities (who move to the UK,) won't integrate. Unlike the 40 people, couples, and families, in my village, who have embraced British culture, by joining the Church, joining in with neighbourhood activities, or joining hobby groups. Every last one of them speaks English, they are all friendly, and they have never expected anyone to bend over backwards to accommodate them or their culture.
Not gonna lie, I used to live in a big town myself that became very multi-cultural (Not London,) and I saw the majority of the town deteriorate, and its identity was lost. We were told by the council that we had to adhere to this rule and that rule, to pacify ethnic minorities and couldn't do certain things in case it offended them (like put a Merry Christmas sign up or fly an England flag when it was a football tournament.)
Yet these same people spoke hardly any English (often none) and moved around in big groups, completely ignoring the British born people there who were doing everything they could to not offend them. They moved to the UK, stayed in the neighbourhoods with people of their ethnic group only, stuck with their own culture and way of living, and carried on living as if they were still in the country they came from.
Makes me wonder why they bothered coming to the UK really, as so many of them make so little effort to integrate with the people who are here. (And as I said, they often carry on living as if they are still in the country they came from.)
After 40-odd years of living in that town, I moved to an upper middle class village in a rural area, and it's predominantly people born in the UK, and English speaking. I feel much more comfortable there. So shoot me! And as I said, the 40 families/households (out of 280 here,) who ARE ethnic minorities, are much more friendly, and they integrate more. They are largely professionals, like doctors, lawyers, teachers, uni lecturers, piano teachers, dentists, and small business owners. They are nearly all middle class/upper middle class.
I wonder if deciding to integrate or not, is a class thing with ethnic minorities who move to another country?
