W_Y firstly Germany and the Netherlands are the only countries exporting more to the UK. than they import from it. Secondly we have no real evidence (you don't either) about how people will vote - so, in the absence of that, we have nothing but opinion polls, which, although not always accurate, are more objective than what your kids think. They have the remain group as being highest amongst those aged 18-29, and we have no other evidence to go on. You are right in saying that the left has an ambivalent position to the EU. particularly after the way Greece has been treated. Corbyn is Eurosceptic, like also the Greens, but wants to stay in so that things like human rights, workers rights etc. can be discussed at a later date - as he said, Cameron concentrated on the wrong things. But, there are some aspects of the Left position which would be easier outside of the EU. such as the renationalization of Post Office, Railways etc. which are difficult within present EU. rulings. The EU. cannot be left as a neo liberal club (which is anything but liberal) but this can only come from within - and that is Corbyn's position. However, I believe that it will be the direction the left voters go which will be the deciding, if unknown, factor.
