It's all a function of geography. In North America, and for the most part in South America, Europe and Oceania and a few scattered places in Africa, Asia and the Middle East, women are equal.
They are not equal everywhere, so woman are not treated equally yet.
Please note that equality does not mean sameness. Looking at wage statistics doesn't make sense when we're biologically different. It's quite possible to be different, but be morally equivalent, and that is the case.
Different chromosomes mean different tendencies. For example, there was a lot of concern about the lack of women in technical fields in the 70's. When all the data came back in, girls were not "deficient" in mathematics, it turned out they all just went into medicine, or non-technical fields as a choice.
