Nonsense of course.
But it is typical that whenever there is good news, in the absence of any sensible way to counter it, people just call other people racists and xenophobes.
As has been pointed out
ad nauseum, the UK always exceeded the EU in terms of conditions at almost every level; maternity leave, holiday pay, minimum wage (which doesnt exist in the EU) were always higher in the UK than the EU.
The argument you make is thus pretty nonsensical, which is probably why you just call people racist.
Incidentally, the hope of raising workers at the lower end was a key plank of the leave campaign - even the In campaign admitted it could be true!

There's a reason lower income groups overwhelmingly voted for it and it's not because they are thick and believe everything a paper tells them, or because they are xenophobes.
