It is too early to tell on any of this. Claim and counter claim, both for and against Brexit are, at the moment, just that. Right now, nothing has changed (as somebody once said
). Talk of the economy avoiding a post Brexit crash is ridiculous, because we are not post Brexit - yet. Talk of thousand of EU workers leaving is irrelevant, because we have not left the Union - yet.
Like I have said before, the great thing about Brexit is that the facts will eventually speak for themselves and all of the white noise will disappear in the rear view mirror.
