I think that you are thinking about the typical stereotype of the occidental woman full of bags and expensive accessories, but I hope this is the exception and not the rule. IMO, in general, in the world men are more frugal than women (they bet more, they drink more, they go whores more often, they value more expensive motorbikes/cars/yatches...), while women think more about the future, the care of children, etc.
On the other hand, I don't think that we are taking this topic as a competition, but simply as a curiosity. You are right that more subjectively than objectively because most of us are giving our opinion rather than scientifically obtained data, but I think that it is valuable to some extent.
I am not entirely sure that's true, the type of men you are talking about is rarer than you think, I believe that men are far more frugal but also this is just pitting to genders against each other and would not win anyone anything if we keep this up.
I think it would be smarter to handle it a bit more professionally and the best way to do that would be making sure that you are doing fine. I know that individually we are different from each other, so try to be frugal and try to find someone else that is frugal and be happy.
If you can do that , then we are going to end up with saving a lot of money, investing in good assets and the result would be nice. Unfortunately not a lot of people do that and the results are usually not that great. This is why the best thing to do is care about your own individual situation and you will be doing a lot better on the long run that way. I hope that it could get to a point where it is only based on you, and not anyone else.
