I'll point you towards something you said (since you're so apt at forgetting what you yourself stated):
That is an absolute statement. According to your own statement the number will be 0%.
It's not me who's pulling numbers from his ass here, Rand. You are.
Have you looked at the numbers of jobs either lost or moved at several banks? Those numbers do not equal "zero". Banks are just the most prominent examples (and the easiest to attribute Brexit to).
Here's a nice compilation. Not saying that it's completely correct but even if it's only 10% of the number stated, that's still not "Zero", Rand.
