Very true. I can see what you are referring to. Even as a very successful law-abiding "expat" I could not stand the tribalism and extreme unconscious racism in my workplace and the society in general. As you said they think all foreigners are children or stupid and they don't respect your knowledge. Life there made me depressed, so I ran away in less than a year and living life now in Ireland. Not blaming the Swedes themselves, they're free to think whatever they like or be arrogant or whatsoever but blaming the false picture and narrative they draw about the country. If you don't respect or want people to live and contribute to your society then don't have a misleading policy of tolerance and integration.
