Can someone please explain why Britain exited/wants to exit Europe cuz i don't understand

I guess the exit was for improving britains own financial situation.. but looking at what happened, it turned out other way aaround.

When I first heard of this. I'm like why would they leave the continent. Would they form a new continent? Did their country drifted away ?

because propaganda ethnic and racial hate are plaguing half the population. Namely the elder and/or uneducated half. People didn't know what they were voting on and voted based on false promises like hundreds of millions of pounds going into the NHS (which isn't happening) and "the foreigners are going home" (Whcih shocker also isn't happening) as well as manufactured statistics like the UK is loosing 17 billion a year because of immigrants and this will stop that.(spoiler alert: No it isn't and no it won't)

Because EU officials have not been elected by the British people.

I have limited knowledge on this subject. If I am not mistaken it is a situation wherein the Brit feel they are better alone rather than being part of a group in which many of the countries are economically weaken. They feel sooner or later Britain might have to bail one of the pother countries. It is in this view that they wan self governance independent from the European Union. I have also heard about referendum and people did not knew what they voted for. If that is the case it is ridiculous. It was a referendum and not some game of who gets more vote.

Don't worry you can't do anything.
