The "doctors and engineers" (i.e. primitive people who can barely speak -- captured on camera, many times) and "cultural enrichment" (i.e. gang rapes and burning and looting) sarcastic memes didn't materialize out of thin air. People can watch news and, you know, actually connect a few dots. Now have one person that was on site and he/she told the story to the neighbors. Now multiply that by a few thousand. There, you have now arrived at the current state of affairs in regards of the public opinion.

Many police departments all over EU withholding information about race / nationality of criminals is not helping things either. When they do that, everybody knows what race and what set of nationalities the criminals belong to.

As a second measure, maybe make life for the law-abiding tax-contributing citizens a tad easier. Government intervention in some areas like real estate prices is pretty much mandatory at this point because they have been asleep at the wheel for a LONG time and things seem like going into a downward spiral to the normal folk. I know this is not a popular opinion on HN but we're way past popularity contests. People need working measures.

Finally, it's no coincidence the right-wing parties are gradually starting to win elections in the EU.

(Bonus points: make things easier for legitimate and hard-working immigrants. It's hard to be motivated to emigrate legally when you are buried under paperwork and the "doctors and engineers" just show up on a rubber boat and are given housing and free food the same day.)
