Although the EU and UK share some problems, there are major differences. Both have short term domestic energy production shortfalls and an aging workforce due to demographic changes.The pound is headed to parity.
Honestly, the whole of Europe is in a huge negative paradigm shift, similar to what occurred in the US in the 1970s. Just like the US in the 1970s, Europe’s global economic standing is going to drop considerably in the next few years.
In the early 1970s the US had to start importing lots of energy after local oil production peaked, competing with Europe and Japan for the same energy resources. The loss of cheaper local energy caused an economic paradigm shift that echoed throughout the industrial economy severely hurting several industries. This was made worse by much of the top engineering talent being siphoned off by the weapons industry.
The same thing, but a little different is happening to Europe right now. Europe has been falling steadily behind the US and Asia in technology. Now because of the mistake of relying on Russia for their energy, they have the highest energy prices in the world, and they will for the foreseeable future. They also have the highest taxes and regulatory cost in the world, and on top of this, their workers work less hours than any workers in the world. They *might* be able to swing this if they were leaders in technology, but as I’ve said above they’ve fallen deeply behind. For instance, California spends more on R&D now than Germany, France and Britain …combined!
Now europe is getting an adjustment just like the US did in the 1970s.
The UK suffers from chronically bad investment, inward investment, workforce training and incredibly bad government. Brexit has destroyed the trading relationship with the EU and there is no sign of replacement any time soon. The London centric nature of much of the economy, investment and policy is a real weakness.
Much of the UK economy is based around very high housing costs, both to buy and rent. This means that ordinary people have most of their wealth in an illiquid asset, or can't build up assets at all if they are renting. This is different from most of EU where housing costs are much less and in some cases super cheap.
The UK planning process is almost as slow and cumbersome as Germany's. It is really difficult to get transport, industrial or energy infrastructure built.
For these and other reasons I think that the EU is likely to suffer a short sharp recession and then grow moderate ly fast, the UK a much longer recession and then struggle to grow.
