I agree with the majority of your post and share your optimism re the resourcefulness of Americans!
I would only disagree with China's potential. They have 1.3B people and have embraced capitalism; they'll be able to grow internally for many many years to come with their current model . . . with one caveat!
I think the Communist government will struggle trying to keep its citizens under control. Idealistically, I don't believe that capitalism and communism can coexist for a long period of time. I would argue that the "great firewall" will not be as effective at controlling the people of China as the "Great Wall" + China's geographic isolation has historically been.
Like you, though, I share great optimism for the future of the US and will be devoting my time doing my best to take advantage of the many great opportunities that are arising from these times of tumult!
Best,
