I think personally that the main problems in the developed world were globalisation + large scale automation, it completely destroyed the power the average worker had, and power directly means money. Inflation is only low because better technology and bigger markets are now available which automatically makes everything cheaper to make, but even that isn't enough to compensate the loss of power of the middle class.
