"Dictatorial, greedy, self-promoting", well those are all terms which apply very well to Boris Johnson, Nigel Farage, Theresa May... any amount of politicians.
"I pay for my health care" I think you'll find a great disparity between what you pay for health care and what it actually costs.
I think the EU has done a very bad job promoting what it does, governments invariably take the credit for EU funded initiatives and always blame the EU when they cock things up or impose unpopular legislation.
I am a European, as far as I am concerned the way the EU is run may not be perfect (show me administration that is!) but it is still an awful lot better for those of us who live in Europe than a slew of little squabbling uncooperative countries who don't communicate and end up shooting themselves in the foot while they try to shoot their neighbour in the back.
I don't see anyone telling federal republics like the US or Australia that they would be better off if all the states were disunited, scrap that greedy self-promoting dictatorial federal government, I wonder why that might be. Cui bono?
