It is common knowledge (confirmed by very many migrants themselves) that the migrants are young men and in very good health, because they come to settle in europe for economic reasons in the very large majority of cases
And if they succeed to settle down permanently, they make to come their family members which in 9 cases on 10 is very numerous
If such a thing as economic refugees or immigrants exist (personally I don't believe in borders), lots of them are probably fleeing from the world we created. Exploiting the people and resources of Africa and other continents happens since centuries and didn't stop just because we made slavery officially illegal. If you don't like them coming here I suggest we stop buying Nestle, Nike and Apple products (along with basically every other product manufactured by global players). We all have blood on our hands and are responsible for wars and poverty as long as we want to maintain our living standard. By the way, that's not an opinion.
