People don't really care about men unless they're beyond the median bell curve threshold (rich/white/etc). As if that's what defines a human experience.
In truth, I hardly find these statistics surprising.
Culturally, men are often seen as more dispensable, as they are not the ones giving birth. They are also taught to be more "tough", which leads to less visits to mental health professionals, and, subsequently, deterioration of mental health issues.
according to my biology teacher, this is not cultural but rather a biological fact prevalent in (most? all?) animals - not that this would help in any debate
What exactly? Dispensability of males? It is indeed common in the animal world, though not universal; besides, we don't struggle to survive as a species, and culturally evolved to be humane.
Interesting offside note from an old 1958 experiment that I recently read on attempts at raising Grouse (extremely difficult due to their ineffective immune systems), but one test batch lost all males to disease. Eventually, one of the hens took on male mating mannerisms and behaviors with the other females. The other females self-ovulated and laid unfertilized eggs. It was only during autopsy that the "male" was determined to be a female because it had convinced the researchers so well.
Biologically, males are a necessary component (under the logic of "at least one") of dimorphic species but people really should ensure that the limiting factors aren't largely based on primitive sexual and reproductive requirements. People just need to take better care of each other, period.
People don’t care about white men generally (hence terms like “white trash”). Rich, famous, highly skilled athletes/musicians/scientists/actors/politicians/etc are what people care about. Ultimately it comes down to “what have you done for me lately?”
In other words, people care about themselves as a rule, and the extent to which they care about others is related to what utility others can provide to the “carer.”
