My hope is that supply chain issues will make clear the downsides to execs (not just the workers) and governments of externalizing all manufacturing abroad and out of reach. Look at the chaos caused by a pandemic, now imagine war or purposefully using supply chain as leverage.
This is all momentary situation caused by the pandemic. In one year, people will not even remember this. Companies will not spend billions of dollars unless they have no other option.
I don't think you're necessarily right this is temporary. But companies always have the option of just not producing. If no one has blue paint, for most uses, the consumer just buys another color and grumbles.
And the things that are most likely to have a shortage would be those things that are cheapest produce a large scale in just one part of the world, so they're things that would be hardest to replace.
