I mostly expect the US to enter a Lost Decade of low growth+high inflation, and for China to inherit the world economy.

Sounds about right. I think our Canadian economic managers, as neolib as they are, are preparing to respond with various public spending on infrastructure, housing, green tech, mining and processing, and military. I think it’s likely to be at least somewhat competent. That said given our massive exposure to the US market I’m still afraid for what savings I have.
