As you can see the recent Brexit in england, trump in US and RSS in india , why is there sudden rise in right wing politics?
Imho it's the too many bad choices made by the politicians lately.
Let's see the picture before everything blew up: people had a pretty good life, pretty stable jobs mostly, some even grew pretty self-suficient to allow themselves to get .. lazy .. or to dream of 4h working day since the money was enough. Immigrants (especially from eastern countries) were not loved, but they were accepted.
Then Lehman Brothers & Co colaps came.
By far, the biggest mistake was to help out the banks after their colaps, using our money. People's life became harder. Internet and media showed the truth that bankers just got richer from this on our expense.
"Because banks are vital for economy" bullshit.
And when people's way of life degraded just enough that everybody feel it, the huge wave of immigrants came: different culture, different color, different smell and way cheaper workers. How would western people like that, really?!
I am from Eastern Europe and I know how we are seen by W. Europe because we can make a living with less money and we can "steal" their jobs. Now multiply that x1000.
In the eastern countries the governments made a lot of money cuts to cover ... basically the expenses cause by the banks bailout.
All in all, everybody grew angry against the "current" governments and all their possible allies. It happened that the "alternative" to be the right wing.
This was Europe. In US the banks' issue was even worse, people lost houses, jobs, .. the current candidates for President are worse than weak (I mean, The Lady and the Trump. Really? US has enough human material for better, although they have a long history of odd choices, Bush Jr being one living example).
