It's not a defense of the EU, the "eurocrats" have little power on the things mentioned, the power is in the hand of our own leaders at national level. Blaming the EU on all subject won't fix anything, if you want to blame them do it when they are actually responsible.
For example the refugees in France and the problem in Calais, from a french standpoint there is only one culprit and he is named Sarkozy, he is the one who drafted the moronic agreement with the UK, then a few years later he thought that it was a good idea to downsize the Police, then he decided to get rid of Gheddafi when it was said that the latter financed his political campaign.
But if you want to blame the EU we can talk about their opinion on monopolies, the fact that they forced EDF-GDF to downsize because they were too big and the general lack of protectionism, that's an issue for me and I'm sure I'm not the only one.
