@livinglava,
If you believe that other cultures should be judged by Western standards, or that Western standards are some "universal" standard, then it will be difficult for us to find agreement. I can answer these questions from the standpoint of Western culture. I don't see any value in discussion mythical "universal" culture.
Our culture is changing. The way Americans saw roles of women and men in 1818 is much different than 1918, or 2018. Of course many other things have changed, the way we view work, raise children and spend leisure time are all markedly different. Our society functioned in any of these time. But people in 1818 are going to answer this question about "gendered gift giving" in 1818 (when I believe there were courtship rituals) quite differently than people will answer in 2018.
Our ideas of the roles of men and women are changing pretty radically. This corresponds with other drastic changes. The way we work is changing, we are in the information age. The way we view marriage has dramatically in both the temporary nature of marriage and the people who are allowed to marry.
This question can only be answered by looking at the needs of our culture, right now in 2018. There is no universal absolute truth here.
