Yes, people with decent education are almost never causing trouble, no matter the country of origin. They can find legal paths to improving their lives, while migrants with difficult background (and their children) have very difficult time doing that. Sweden isn't like the USA in the 1800's, you need education and decent language skills for any good jobs. Free education is no silver bullet that suddenly turns masses of illiterate people into doctors and economists, because even under such system there's competition for university spots.

Sweden quite simply took in way too many people who would have required a lot of help to integrate, stuffed them into bad neighbourhoods and gave them free money. I'm sure many companies have benefited from this supply of slave labour, but for the society as a whole it has been a disaster.
