What specifically isn't working in what concerns immigration and how has the way immigration was handled in the last 20 years been a failure? Please provide specific examples. I live in an European capital and haven't seen any of these issues that immigration is supposedly creating. AFAICT theses issues only exist in the minds of people, and thus in the media. Regardless, let's say I'm wrong and immigration is indeed creating some issues. Are these issues really so important relative to other problems a state might have that they command the amount of attention immigration gets? I call bullshit, it's purely a wrong skin color problem.
