Apologies for previous post, I was unable to take your question seriously although I am taking the coronavirus threat very seriously.My serious answer to your question is that it is not the end of US surfboard production, no economic collapse lasts forever and I don't believe there is going to be an economic collapse which matches the great depression.
The GFC has done us us a favour to prepare for this crisis - some banks and lending practises were rotten to the core and the rot has been removed. Our governments have also come a long way since the great depression and are more willing to prime the pumps in times of strife. Even those of us who keep our jobs will pay for this for sure - less retirement fund than if the crisis had never happened, higher taxes to pay back all the money our governments threw at the situation, reduced standard of living through inflation perhaps, but thats not the end of the world and surfboard production.
I have promised myself that if I come out the other side with my job intact I will buy a local (Regional Vic) custom surfboard even though my two pu/pe Chilli boards look like they last a while. I'm sure there are others with a similar idea.
