Immigration is a relatively recent arrival in Europe. Traditionally they've been leaning more to the emigration side of the issue. Right up to the recent past, they exported excess people which kept the job markets in Europe more stable. I can understand their unhappiness with the less acceptable consequences of immigration (the initial flooding of job markets with workers willing to accept lower wages, and the cultural clashes as the new arrivals try to fit into their new surroundings but hating to lose their original cultural identities).But immigration has always been a factor in our traditions. In the long run, immigration has been beneficial in bringing in new ideas to the US and generally the immigrants are good people who quickly become Americanized. Generally this occurs within one generation. Even the anti-immigrant problems we are currently having are not new here. Now it's the Central and South Americans, along with Mexicans who are North Americans, who are the ones angering the Americans already here (even those whose parents were immigrants). Before them it was the Italians, Greeks, Portuguese, and Irish.It's an issue the world will have to resolve pretty quickly because with climate change and the permanent flooding of coastlines and low river valleys and basins, there will be a lot of people moving. There are no longer any uninhabited places for these people to go. We will all have to "move over" to let them in. If we don't, then there will be walls and defensive war and invasive war and a return to chaos. Only tolerance and a willingness to share will avoid this. Very sad that not enough people, especially among the leaders, can see this.
