It may be that I am not directly affected in some cases, but I'm pretty sure I'm going to hit a wall sometime trying to figure out whether the uri in some cryptographic siggy is valid or not.

I do work for Vestas in the UK, you are exactly right. Blade building is currently very labour intensive, I've actually worked on the shop floor for a week. There were protests at the Vestas factory on the Isle of Wight when it was closed down, even though it clearly didn't make economic sense to builds the blades in the UK with high labour costs while almost all the blades (for V82 1.6MW turbines) are sold to the USA and China. So Vestas decided to build new factories in the US and China instead.

The bigger question is, why is Vestas, a Danish Company, the biggest wind turbine producer in the world with ~25-30% market share? How come countries like the USA, Germany who gave billions to Boeing, Siemens, GE and the like for wind turbine research and had nothing to show for it, and everyone ended up using the iconic three bladed "Danish" design?

The answer boils down to having smart people in the government, avoiding overly ambitious expensive projects that often ended in failure, having a long turn vision in providing continued support in good times and bad times.
