But once you get into a deflationary spiral (which starts as you may well guess from ever small deflation) you have not much options available to break out (WWII as such a breakout)
Why would you
want to break out? Having my savings continually gaining value doesn't sound so bad.
Because you think only from a consumer's point of view. It's not bad for one person (may be even for two or two thousand) but it is very bad for the economy as a whole. Take the side of a producer and you will get a clue
I don't see the problem for the producer. Could you explain it?
