I would look at such graphs with a grain of salt. Arbitrary comparing prices leaves out too much context.
If you look at the price of lemons in the US in isolation you get a different picture.
In the United States, the retail price of a pound of lemons stood at just above two U.S.

A better indicator is available income and its shares on expenses.
I didn't figure out the real reason for the shortages, though it seems here in Europe we are quite ok regarding consumer goods (for the moment I add, but we still produce a lot of foodstuffs and other daily use goods this helps now). The EU is largely self sufficient in this regard. At least one system with a complete supply chain.
For industrial base products there seems to be long lead times and difficult procurement.
The main reasons I get are:
1. Corona disruptions by countries like China which made themselves the workbench of the world (and we even actively supported it) but are now producing regular bottlenecks by panic Corona measures and Xis shenanigans. Also other countries fall under "Panic Corona measures" e.g. Malaysia.
=> unreliable suppliers
2. China itself and Xis way of the Mao. I suspect huge hamster buys orchestrated by the state to prepare for whatever CCP is "planning".
3. Resource rich countries not producing enough due to restrictions
4. Hamster buying in general by companies able to afford it.
5. Global chaos in transportation
So putting all eggs in one basket was not so smart after all.
Regarding the return of industries to the West will only happen to such an extent that an emergency upscalable base is kept where production is not economical in the West. But the unreliabilty of CCP driven China may change that substantially
And the energy change and automation will localise a lot which is now shippped around the world.
It would be highly advised to diversify the supply chains as much as possible. This would better reflect a global market than the current concentration on one region.
The industry should also distance themselves from autocrats as in the end they always prioritize the support of their oppression apparatus over economic stability.
