I think you make a good point about your cousins children. I believe if the EU could survive for another decade or so, it will be in a much better shape. IMO the politics of free movement inside the EU changes the lives and behavior of those affected(e.g. students having the chance to live & study in a totally different culture and environment) in a way that makes is almost impossible for them to accept a reversal to the old status-quot. When the generations that are currently criss-crossing in the halls of european universities will get a chance to influence the politics I believe we'll see a much more aligned "european identity".
