This is one of narratives we see in the Swedish media, and from the political left: the rise of the Sweden Democrats is due to increasing economic inequality, hopelessness, and so on, and everything will become better if we just raise taxes and pour money into welfare.

I don't believe this narrative at all. TL;DR - it's the immigration, stupid.

Immigration has never been popular in Sweden, but it has not become an important issue for voters until the Reinfeldt government came to power, due to the simple reason of volumes. Immigration doubled under Reinfeldt, and he promised/warned it would increase by another 50% in the next four years.

10 years ago, immigration was say the top 8 or top 10 issue for voters. Now it's the top 3 or top 4 issue. People have the same view of immigration now as they had back then (mainly negative*), and the only thing which has changed is the volumes. To me, this explains the entirety of the recent election result.

* According to the very big and anonymous SOM (2012) poll made by the university of Gothenburg, these were the views on immigration in Sweden.

"Recieve fewer refugees in Sweden"

Good idea: 45%
Bad idea: 29%
Neither: 26%

"Recieve more refugees in Sweden"
Good idea: 18%
Bad idea: 50%
Neither: 31%

If you look at the views of the Moderate voters, you get this result.

"Recieve fewer refugees in Sweden" (Moderates)

Good idea: 53%
Bad idea: 21%

"Recieve more refugees in Sweden" (Moderates)
Good idea: 12%
Bad idea: 57%

This also explains why the Moderates had a huge loss of voters (4 percentage points) straight into the Sweden democrats. This is equal to more than half of the total election gains of the Sweden Democrats.

It also doesn't hurt that the Moderates have run an atrocious defence policy (Moderate core voters are defence friendly), while the SD has a very strong pro-defence stance.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
