This is a real thing for millions of people, particularly in Yorkshire too. Like I said a couple of days ago, when you actually talk to real people and get a grasp of what problems they have, you begin to understand that under the current regime (Yes that includes our own government) there's nothing positive in the future.
People have nothing, no future prospects, working 8 hours a day for very little. Wages aren't rising while the cost of living is skyrocketing. Houses are too expensive, schools are full, the NHS is struggling. They see an option for something new (with expectations of a brighter future) and you can bet they'll take that option. If you can kick the government in the bollocks while you do it, it's a bonus.
That's why large chunks of the poorest communities have voted to leave. They've been abandoned by a government that's focussed primarily on London over the last 20-30 years. It's as much a protest vote as it is an "immigration" vote, a "sovereignty" vote or whatever else.
