You have asked a lot of questions. You are really asking how exactly this model does not jibe with the realities of the labour market. My interpretation of that statement is that the labour market, unfortunately, is still characterized by extensive discrimination against women in terms of wages, and in other areas as well. As a result, a complaint-based process will certainly not resolve such an extensive and persistent problem. If we were talking about a one-time issue in a specific workplace that was limited in time, it might be possible to use the complaint-based method. However, as we all know, this is something that is very common in workplaces, and it is also a problem that has been around for a long time and that we have been unsuccessful in addressing. This model simply is not suited to dealing with the realities of the labour market. I don't know whether that answers your question.
