man is more necessary for the general survival of our culture/social standard than a women.
If I understand the halacha correctly, that’s not what its saying. Its saying that because men can do more mitzvos,you save them. Not because they are more necessary for survival, because you need more women than men for that.
[Now AZ should chime in that not in the current climate because there is a glut of older women so its EXTRA important to save a man for the age gap]
