>3. People turn to these parties because like in the US, the political landscape in Europe has shifted to the right, economically. A blatant example of this is that both the center right and center left are fully supportive of TTIP. The only other notable alternative besides the anti-immigration parties is the Greens but the Greens are highly opinionated about many things that tends to turn people off. Plus they have been there since forever and not achieved much so people do not see them as "change".

The first time this happened, in the Great Depression, there was also a steady move towards far-left parties. This time, the far-left has been doubly crippled: once by the lack of the Soviet Union to point to or turn to for examples and instructions in how socialism can work, and secondly by Western governments equating the far-left with domestic terrorism (which hasn't been true since the '70s-'90s period) and cracking down.

I wonder what our current situation would look like if the political spectrum was allowed to extend sufficiently to the left that Bernie Sanders and Jeremy Corbyn (bog-standard social democrats) couldn't call themselves revolutionary.
