But still, not to worry, at least we won't be dead! Every cloud, eh?
Well about that part, considering the UK government is doing their absolute best to kill the NHS, which in turn will almost assuredly mean a US style health system sometime in the future, it will mean that poverty (as in decrease financial wealth) will actually lead to more people dying, and since the experts opinions on the UK exiting the EU is that it will lead to a poorer UK, then by extension that means that you will likely see unnecessary deaths caused by this.
So yeah...
