As someone born and raised about four miles from Easington, where Billy Elliot was set, and was in my teens at the time (yes I am almost that character), it just made me chuckle. There's no real reason you should know the ins and outs of the UK miners' strike.
For info - it lasted about a year - and was the biggest industrial action in the UK in over a century. In particular it affected large swathes of the North East and Yorkshire as well as South Wales and Scotland - and many other places too to a lesser extent - all mainly working class areas where mining was the key form of industry. In 1985, just before the strikes started there were about 175 working pits in the UK (employing about 187,000 miners) - by 1994 there were only 15. Today there are none.
Obviously my knowledge of American regional history is non-existent - and hadn't heard of Alexander Hamilton until 2015 even though I've held many $10 bills.
