I had a friend that voted for Brexit. When I asked him why, he said that his grandfather was able to buy a house and take care of his family on his salary. His father was able to do the same. He said, these immigrants come in and live two families to a house and are willing to work for far less. He said, I don't want that type of future for myself.
No amount of telling him that -- the people that caused this issue are also benefitting from Brexit -- could convince him.
Was weird because I wasn't an immigrant but my family was and he was cool with me.
