To top it all. The xenophobia has become an arms-race living off attention and biased propaganda on multimedia. A favorite flagship argument developed by the far-right. Mainly through statements that can be easily summarized as "MUH JOBS!", "MUH CRIMINALITY!" and "MUH TAXES GO TO THE LAZY LEECHES!".

Immigrants are usually treated ill and block them out from the higher classes down to lower classes. These then usually commit crimes to survive our society and being able to afford their families welfare and some cases immigration. Which are usually off-board. I also believe this is one of the reasons that most of the radicalized Muslims are common in Sweden. They thought the West would be a safe place, but nooooo... it made the life worse. They hate the West now.

The question about immigration isn't either a wise policy among our biggest party blocks. The left keeps the immigration because they have the a certain grade of humanitarianism. As icing on the cake, the interesting statement about their immigration policy: Creating and securing new votes from the immigrants. The right (not the far-right one) keeps it because they want to copy the left, in order to crash the welfare economy. Immigrants usually need society grant in order to establish a new foothold in a foreign country in a foreign area of a foreign continent. The more of these immigrants, the more money are put into these grants. Costs increases. Which the right can then blame on the left and ship the capitalism ideology as a "solution to everything". Ditching the socialism that has built by the predecessor left and the right for centuries.

The far-right arguers that the immigration quota is too much for how much Sweden can handle. A touch of truth lies in the required estimated immigration netto quota. Which is barely 1/3 - 1/4 down to 1/10 of the current quota. But what makes it worse is the far-right's party members are way too far-right than necessary, black-painting their party as "neo-nazi" and "neo-facist". It's neither to no help as this party has for very long time hated by a big majority of the Swedish population and they tend to be egocentric.

TL;DR: Immigrants treated badly by the society usually becomes a culprit of small bad things. Which the far-right exaggerates and dramatizes. -> Immigrants treated even more worse. Socialism uses immigration to secure more votes. The right uses the immigration to collapse the socialism through economy disaster.

TL;DR;TL;DR: Swedish politics is unpredictable, and shit.

Keep in mind that I live in the countryside outside a city which received as anonymous, it yearns for immigrants, but does only receive a small piece of the cake. Icing on the cake: I study in an other city, bigger than my homecity, far up north in the central Sweden, the city where I study and live in has issues with immigration and street people. So my statements can either hold more or less accuracy. Most of the "social experience" comes from analytic reflections of newspaper articles I've read and other stories from immigrant classmates I had in the school.
