> What do you mean by "number of dollars approximately doubles in 2"?

I think OP was talking about monetary inflation. We nearly double the money supply so it should translate to a nearly double price inflation.

That is not how inflation works.

All thing being equal. 2x monetary supply should translate to 2x price inflation. It’s literally how inflation work. The reason we don’t have that’s crazy inflation is not everything is equal. Mostly at natural the economy should deflate right now.

You can have negative inflation, but don't central banks work really hard to avoid that because (the theory goes) deflation will kill spending?

Pretty big difference between "we want to but we can't" and "we can but we don't want to"

Yes, and what's your point?
