I live in Malmö, where 43 % of people have foreign backgrounds (born abroad or with foreign-born parents). In my neighborhood, that number is 86 %. Sweden is heavily segregated, and not enough has been done to deal with it. Immigrants with degrees has had trouble in the past to make use of it, either because of overbearing bureacracy or lack of connections. Look at 2) and replace city with country. Fortunately, a lot of people and organizations seems to be waking up and trying to do the right thing. My trade union has started up language cafés to allow people to network, and some large construction companies just published a Swedish-Arabic dictionary for industry terms. My parents were the children of poor farm-hands, and thanks to free education and government loans, they both got degrees and careers as professionals. If we steer clear of prejudice, I don't see why class journeys like that shouldn't be possible in the future.
