Tech is the problem. The internet is global (or perhaps two or three regions), and winner takes all - so global value creation is being experienced everywhere, but being monetised in the US stock market. Take tech out of the equation and the US is pretty much on par with EU, and China and India are just burning the coal for everyone else.

Anyway, the idea stuck with me. Anyone who wants to reject the point will have an easy time as it's such a broad claim, but I think it's worthy of reflecting on, and perilous to ignore.
There's a lot of ink splattered about technology these days, of course, but it's still rare enough that the larger picture of what's going on historically in terms of power structures is seriously reflected on.
