A common refrain in the Manosphere is that single (often divorced) women in their 50’s are in for an awakening. They no longer can command the attention that they did in their younger years. In effect, it is said, they then know what it is like to be a guy.
IT does seem to be true that females are treated better than males, even when there can be no expectation of an intimate relationship. I noticed this when my older sister was always treated better by people than I was. Perhaps some of this was due to my INTJ Death Stare, but even after taking that into account, she was treated better. People would offer to do things for her, she would get lots of opportunities, doors would fly open for her, etc.
This was really my first lesson of men have to do, women just have to be. Men have to work and scrap to get anywhere. Nobody “covers” long term for a man. This is the way that it has always been, and will never change.
As for those 50-something women, their appearance has diminished, and the magical spell that it had over people in general is mostly gone. They no longer are of use to the tribe as baby-makers, so they must be useful/appealing in other ways. Often at that stage, they have little to fall back on. Perhaps they are a gracious grandmother, this is considered useful. Perhaps they are a bitter bitch working a useless job, this is considered to be not useful. Naturally enough, most do not want to be judged (like a man), but that does not stop people from doing so.
