Recessions are cyclical, usually we get one each decade. So I would agree we are due another one, when we haven't yet fully recovered from the last one, although it isn't completely inevitable.
Brexit negotiations will decide the future of the EU project though whatever happens. There will be a power struggle over the outcome between the Eurocrats who are only interested in "the project", and European business who want to continue to freely sell their products and services to the UK.
The Eurocrats want to punish the UK for having the audacity to leave, even if it seriously damages European economies in the process, as a successful post Brexit UK is their worst nightmare.
Vag BMW, Mercedes, Fiat, Citreon, Renault, Peugeot (and that is just one industry) have no interest in this. They want to run successful businesses without being hamstrung by politicians, who are almost by definition, too stupid to run a corner shop, never mind a global business.
We shall see who appears to have won at the end of the process, but I cant see any long term outcome other than business being the winner.
Stupid politicians need money to waste, and they need businesses to generate it so they can take it from them and squander it.
The markets always decide in the end. Theres no way around it.
