By far the best analysis of this mess is to be found in David Goodhart’s book, The British Dream: Successes and Failures of Post-War Immigration. Goodhart has had the guts to challenge the liberal consensus that held that unchecked immigration was simply marvellous, without ever explaining whose interests it was meant to serve. Like many of us who grew up in the monochrome Sixties, Goodhart says he is happy living in a vibrant, multi-racial society, “but I have come to believe that Britain has had too much immigration, too quickly, and much of it, especially for the least well-off, has not produced self-evident economic benefit”.
