Brexit is a rejection of globalisation (How to save the world)

https://www.theguardian.com/business/2016/jun/26/brexit-is-the-rejection-of-globalisation This article by the Guardian is about Brexit, this long article talks about the cause and what effect Brexit will have in the future. One aspect of this article that I was particularly interested in were the parts where it noted the failures of the EU, they talk about since its creation that the promises that the EU had made have not been met, giving examples of Italy's economy not improving since the EU began, it also talks about the economically unstable and poorer parts of the UK having the most 'leave' vote, which implies the low standard of living and lack of improvements that people see have caused people to choose this vote, in particular this interesting because the Guardian being a left wing newspaper, it'd be against the idea of leaving, and while the title of the article suggests this, this is not the case with the content involving why the leave vote won, suggesting that the leave vote was justified. In the beginning of the article they talk about the idea of globalization, and how it started back when the Berlin wall was torn down, I believe that this idea of globalization that the articles goes on about is the best way that the world can be saved, the world as one close unit is stronger than the world as separated countries who fight between each other with their own interests in mind, while the idea of the world acting as one single unit it almost impossible in its current state, I believe it should be an end goal every country should try and meet, obviously, Brexit goes against this motion, which is why it can be seen as a problem. The Berlin wall is also a symbol of this unification of the world, as it represented the far sides of Europe, other examples of the world being unified can be seen throughout history, through allied systems, the league of nations, the UN, and the EU, Brexit is a step back from this idea.
