In most western countries this is definitely not the norm. From what I recall, this transformation started to change after WWI in western countries and today's norm is the result of those long transformation.
I will say that the idea of the wife staying home while the husband works is probably not the norm in any fast paced countries now, although we do try to keep it acceptable as Australia is so culturally mixed.
However, in most Asian countries it's still the norm, the husband is the breadwinner. Though it is slowly changing among younger generation as I think we've become much more hedonist and consumptive.This situation affects the relationship dynamic too.
Thanks for reading, have a great weekend.
