I'll repost the link to Jacob Ress-Moggs vision regarding the degree to which we will be able to lower standards after the insanity of BrexShit...

And you can also read how Dominic Raab - the Brexit Secretary, lest we forget - wants to lower employment and welfare standards (like pensions, for example) - in his ideal world, in his book "Britannia Unchained"

His views on funding the NHS are also worth considering.
