Been saying this for years, its so obvious. There is the beginnings of backlashes, Trump being the obvious and it will worsen. Those that are playing politics with immigration, religion and equality think that they can either win over time or care very little for the damage they do to the classes that they are meddling with. Those classes will though grow up more radical, more disaffected and more likely to vote for populist right wing politicians.
The backlash is very slow building and I suspect is not big enough, because the younger millenial generation are living in a giant echo chamber created by educationalists and media. When they reach a certain point and realise how much they have been stitched up, I would expect some reaction and that will be nothing like the quiet mumbles of complaint in this age.
Remember America has had identity politics decades before this nation and trump is 20 years ahead of the UK.
