To start with - I happen to be European. (Finn, living in UK.) I would say that all three of your examples actually confirm what I sad above.
UKIP, Podemos and SYRIZA are all parties that rose to their position of power only after the status quo was already horribly disturbed.
UKIP - While UK feels a bit xenophobic at times, it was only when the financial stability was shattered that a more-extreme-than-current protest movement gained power
SYRIZA - rose to power after Greece economy was first demolished, and then further abused; again, the calm and nice status quo was disturbed
Podemos - I hear Spain has suffered similarly since the financial crisis and is still in the process of starting their recovery

In the U.S., after horrible disturbances, we watch the two parties blame each other on talk radio, Fox News, and MSNBC and then vote the same parties in.
I guess if you omit the civil war, ww1, ww2, the great depression, the financial crisis of 2008, racial strife, 1970s stagflation, and any number of major disruptions from the historical record, youre right.
I meant in recent years, but the 2008 financial crisis was nothing in the US compared to what it was in Europe. The US Dollar was never at major threat of collapse the way the Euro was.
