If I were to make this study I would pick a list of ten things that women report as "bad treatments", verify how does each society/country do in those areas based on available statistical data or even surveys, and correlate with wealth of that society. Obviously there is the possibility that some of these metrics correlate negatively or even do not correlate with society's wealth, but an ethical study should report all findings.
