The future's bright not apocalyptic

According to David Davis, who is allegedly the man in the know, post-Brexit Britain won't "be plunged into a Mad Max-style world borrowed from dystopian fiction". I'm delighted to hear it - though can't help wondering how exactly we got from "There'll be £350 million more for the NHS and everyone'll be better off" to "It won't be utterly apocalyptic". Impressive levels of expectation management (downwards) going on here.
