did women earn less than men for the same job before World War I after World War I or both?

Before World War I, women typically earned less than men for the same job. This was due to widespread discrimination and societal norms that devalued women's work. During and after World War I, there were some improvements in pay equality as women entered the workforce in larger numbers to support the war effort. However, disparities in pay based on gender still persisted, and it wasn't until many years later that significant progress was made towards achieving gender pay equality.
