look what is going on all over the Europe. Generations of children or grandchildren of immigrants who came to Europe in decades after WWII lives in countries to which they have no cultural ties. Their parents of grandparents came to Europe with knowledge of reality of their former homelands and I agree that they worked hard and helped Europe a lot but now we have huge communities of people with no cultural roots, they were born here but they are still strangers. This leads to Paris riots, London or Madrid terrorist attacks, huge criminality in those communities etc. Free or easy immigration is dangerous. We have to tighten the immigration rules, that is my opinion. Let´s welcome people who are interested in working here, who understand that they will have to accept our laws, cultural standards, language - with NO exceptions. These people can give much to our society. But reality is that majority of immigrants have no knowledge about our society, they have no idea what it looks like here and what they have to do if they want to live on the same standard as we are. Only those who will be able to prove all these things can be allowed to became Europeans. Sounds hard? Maybe it is, but in my opinion, it is neessary.
