If you're a factory worker, you might not care that the EU makes the UK richer through free trade. That the EU benefits you overall doesn't matter - you would prefer a system where the pound is weaker, and imports/exports are tough, if it means that the manufacturing needs of British workers are served by British citizens like you. Having a manufacturing job, even if it is less lucrative, is more appealing than having no job and watching the rest of the country enjoy a slightly higher quality of life. Open borders mean you let in foreign doctors and scientists; it also means that you let in cab drivers and factory workers, in greater numbers. The British are pushing back against this. Unskilled workers would rather have a dose of protectionism than the possibility of a vacation in Spain.
For what it's worth, I think that the leave vote will not bring the kind of protectionism the British want.
Putting petrol and groceries on the credit card is getting boring now. How many maxed out credit cards does one family need?
Rich folk keep saying "Why? Why? Why?" and we say "Why not?"
As is (sadly) customary with major elections and campaign promises, I think you'll feel cheated again. There certainly are (were) good arguments to be made for leaving (the inability of the EU to fundamentally change its structure, the EP giving all of Europe the big finger when it happily elected Juncker as president instead of a reformist, the ideal of self-determination); but economics isn't one of those.
"I'm fed up with being poor. I'm going to show those big-wigs that we've had enough! By voting to... leave the EU. Yeah. I'm like, 15% sure it has something to do with the EU."
You can be outside the top 1% and still be significantly better off than many.
You're in the top 10% of the country:
