Shocking level of naivety on this thread.
There will be many, many job losses.
There will be many firms relocating to EU companies. Contingency arrangements are already in place and will just need to be invoked.
Consultation will happen, as firms go through the motions. But the jobs will go nonetheless.
Many billions of revenue will be lost.
Support services will be hit hard.
There will be a recession.
The poorest will - yet again - bear the brunt.
There will be little to replace the lost revenue from financial services, as we don't actually make or do much else in this country.
Investment in public services will be cut yet again.
Most items will be significantly more expensive due to the weak pound and less favourable trading terms.
So no, there is no over-reaction. People are right to be scared. This is real.
