Essentially Islamophobia and the fear of losing the NHS (free public healthcare) has caused the greater majority of the UK's population to deem themselves better off as a Sovereign nation. I personally didn't vote because I'm smart enough to know that it isn't worth the time/effort. Either way the politicians are going to arse-fuck us senseless and there aren't enough moderately intelligent bystanders to unite and do anything about that, so fuck it.
I have already made the decision to invest some money in a foreign currency so that when the pound has finished crashing and stabilising, I can convert it back.
