There is a certain veer to the right broadly speaking, fueled by discontentment over uncontrolled immigration and the (correct) perception that it is in fact encouraged and sustained by the economic and political status quo.

The problem is that these nationalist populists are as socialist as the status quo, so they fail to address the real root cause: the gigantic, irrational, morally corrupt and economically unsustainable "welfare state".

The status quo brings in millions of unqualified "labor" from third world countries as a short term fix to keep the music going, mainly and foremost, because that's exactly what the voters demand. The right wing doesn't even recognize this, so their recipe for more welfare, without the immigration, is even more of a fantasy than the current fiction. In fact, blaming the immigrants instead of the State, as a distraction, is wrong and immoral to a large extent.

Europeans are sick and tired of the demographic invasion, that's true, but they are also morally bankrupt and incapable of taking responsibility for themselves. That is the result of seven or eight decades of socialism, and it's probably inevitable. But because it's not a sudden change from being rich to being miserable, it's hard to harness social discontent in a politically productive way that can bring true change.

Like Argentina, it would take a lot more than the current pain before people are willing to address the root cause. And even then, the chances to succeed will be extremely low.
