The status quo wasn't great for the ordinary people and the only offramp they had was clown world. Brexit should have been a hard lesson proving the people will vote against their own interest if they believe they are also voting for something harmful to the regime they despise.
People weren't voting against their own interest. They are voting against a system which they do not believe worked for them. Saying people vote against their own interest is saying that they aught to just shut up and listen. If you propose policy X and say it will be good for people, and they vote against X, then that is a moment of self-reflection on why people think X is not good for them. That attitude is exactly why people despise the regime above them.
