Neither societal structure or quality of life affect the drying time of cloth diapers in humid places.

Edit - and having lived in both, you're much better off drying things in a hot humid place than in colder ones.

We used cloth diapers in a place that's hot and humid but seasonally cold (the US Deep South). Outside on the line, diapers dried a lot faster in the summer than the winter. We ended up having to buy a used dryer for winter use, because they simply didn't dry fast enough to be ready by the time we needed them.
