"Fear Uncertainty and Doubt.
The remainers are playing up the scaremongering to extreme hype levels "
You seem to have a pretty low opinion of the leaders of the industry sector that I presume most of us work in. If there was no good reason to stay do you not think that logically they might just say that? Presumably they mostly make sound, logical decisions based on evidence, experience and knowledge, and yet mysteriously they all seem to be lying and spreading fear when it comes to the EU.
Occam's Razor would suggest it's you who is wrong.
