I've been thinking about this for decades, long before the Internet and certainly long before the Manosphere (which is why I know so much of it is adolescent nonsense).
Ingratitude is one of the worst vices in the world. It's a species of envy: "You've got it, now give it to me."
Men invented everything in the world. Okay, maybe not everything. Just 99.99% of it. Women did invent some things (who has ever heard of Grace Hopper?) but those women are extreme outliers.
Men invent, discover, create, then many women follow, feel sorry for themselves, start whining about a non-existent "oppression" and "patriarchy," then howl, "Give me my cut! No, wait! Give all of it to me because I can run it just as well as men!"
I've had women tell me, "Men are responsible for all the problems in the world" (what is this, 1968?) All of them were unmarried, middle-aged, and made about $45,000 a year from jobs created by men. Gratitude? Appreciation? What are those? But envy? Certainly.
Women would literally be up shit creek if men didn't love them. Those goofy evo-psych/Manosphere hallucinations about it all being about sex - goofy as hell. It's about love - and if love didn't exist we'd be on the same level as cats and dogs. Both men and women.
I've mentioned before about "The Little House on the Prairie Books," which everyone should read. There is a scene in which Laura Ingalls Wilder's father ("Pa") builds a house basically with an ax. He chops down trees, has the horses haul them to the site, makes logs out of them, builds a house, then splits logs lengthwise, smooths the insides, then uses them for the floor. Then he builds the furniture!
This is what he did for his wife and children.
His wife ("Ma") did the cooking, cleaning, cannng, etc. Could she have built the house? BWAHAHA!!!
And I don't think Pa was as big or strong as me. I know what he went through, since my father was a general contractor and I started building houses when I was 12. It was pretty horrible. I almost got killed once and hurt myself several times - smashing your thumb with a hammer is not funny, no matter what the cartoons tell us.
I once found the tip of a guy's finger when he fell off of a ladder and grabbed the wrong thing. I've also seen guys run power saws over their hands and fingers and shoot themselves in the feet with nailguns.
I occasionally ask women what would happen to them if men withdrew from running and maintaining the world. No more water or electricity or food. Poof! Just like that.
One woman told me, "Men wouldn't get paid," to which I responded, "You just don't get it at all, do you? Men invented everything in the world."
Carl Jung understood this. Men are culturally indispensable since they created everything and women are biologically indispensable since they have the babies. Until we create artificial wombs and sexbots!
I've mentioned before about the wisdom of the story of the Garden of Eden. Women's greatest flaw is envy (the "serpent" is a symbol of envy) and men's greatest flaw in listening to envious women - and apparently being unable to perceive that they are envious!
Envy wants to drag people down. It shows no gratitude and appreciation. So when women put men down and demand things from them (especially without giving anything in return), those are the main signs of envy. Do nothing for them. Stay away from them.
This envy of women, with men unable to recognize it, is part of the Battle of the Sexes, which has now apparently taken on the dimensions of a war!
Marriage rates have collapsed, which of course women blame on men - since they refuse to look in the mirror. And babies being born? Not so much anymore.
Why should men get married and have children? What's in it for them anymore? Being the object of envious attacks and and having every problem in the world blamed on them? Who needs that?
These problems have happened in the past, along with imperial overstretch and catastropic economic problems.
Yet people don't learn from history. In fact, if there is one lesson from history everyone should know, it's that people don't learn from it.
