I think it comes down to people being poor and scared.
And angry that since 2008 their standard of living, which was pretty damn good, has slid off into a distance so far that many people dont even remember a time when it was good.
Its the same as here. Its the same as many many places in Europe, and probably worldwide (but Im not up to par on the world news)
people see that their children have less opportunities than they had, and are being saddled with huge debts before they even start, and costs of living that are eyewatering, and likely to stay at home for years due to property skyrocketing.
They see services cut to the core
When people are scared for their own survival its easy to pitch them against 'others' who may appear to be getting something that they dont get, be that financially or even in attention and 'special status'.
It was always going to happen, because its the natural consequence of really successful unregulated market forces.
