So, the USD, which has been inflated every time they expanded the empire over the last XXX years, but their citizenship/working class feels it's deflationary, so they keep chasing it as fast as they possibly can...?
You're claiming inflationary currencies have never been suitable.
Nonsense. Until recently, we've seen the currencies of large empires like Britain and US do nothing but inflate, yet their currency and their economies function just fine.
No, I'm claiming deflationary currencies are unsuitable. Inflationary currencies are much more desirable, which is why the world powers tend to have slightly inflating currencies.
