Lol, as if the vast majority of people worldwide don't do what is best for themselves first and foremost. People are the centre of their own universe, it's nothing to do with nationality.
This vote was passed by older right-leaning, working class people who didn't want to be told what to do by random EU nobodies. And when you see what has followed it only adds fuel to their ideologies. But worst of all was the general apathy from the younger generation, i.e. those who will be more affected.
