As everyone with half a brain knows, the marriage rate is a little over 50% and is estimated to soon drop below 50%. Obviously, many men no longer feel marriage is viable option.
Now let's apply some Game Theory to this. And I don't mean what the Manosphere considers "Game."
I'm referring to the Game Theory outlined in Robert Axelrod's The Evolution of Cooperation.
In that Game Theory there is what as known as Tit-for-Tat: "An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action," said Wikipedia. "If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not."
In simpler terms, you can put it this way: "You treat me like shit and I'll treat you like shit." It's revenge, really.
On the hand, treat someone nice well and you often get: "You treat me well and I will treat you well."
In biology, this is known as "reciprocal altruism." It's also known as "behavioral assimilation," a "process in which they tend to match their own behaviors to those displayed by cooperating or competing group members. Therefore, if TFT begins with cooperation, then cooperation ensues. On the other hand, if the other party competes, then TFT will lead the alternate party to compete as well. Ultimately, each action by the other member is countered with a matching response, competition with competition and cooperation with cooperation."
Again, this is common sense and has for known for a long time, as in "Do to others as you would have others do to you." The bad aspect of that is "Do to others as they do to you," or "An eye for an eye and a tooth for a tooth."
Now let's apply this to the Manosphere. In a number of cases (that number being large enough to be noticeable) men are supposed to cooperate but women are trying to cheat. Do I need to give you any examples?
Okay, I'll give you one, and it's a big one. Men are supposed to do the heavy lifting when it comes to women. Approach, ask, pay. There is supposed to be payoff to this, and I don't mean sex. I just mean being pleasant and friendly and appreciative, and not having to suffer some humiliating nuclear rejection.
Ultimately there is the hope of a loving relationship, marriage, some kids. If that happens there is the strong possibility of her divorcing you and taking your money and kids and the damn house for that matter!
Men are doing their part, but many women are not doing theirs. Worse, they think they're victims!
Let's put it this way: men give and women take. Not in all cases, but enough to be noticeable. What will happen, and is happening? Cooperation is going to break down, and is breaking down.
Women expect men to give but don't expect to reciprocate. When there is giving but no return of it, what will happen is withdrawal and/or revenge. "You treat me like shit long enough, and I will treat you like shit in return."
Feminism (which is still alive in women's behavior if not in articulated ideas) is about take but not give. Or perhaps, taking a hell of a lot more than is given.
The Manosphere is the reaction to feminism. The Tit-for-Tat. It's not cooperation. It's become a particularly nasty competition. Men either go PUA or MGTOW.
Obviously this isn't going to end well. At worst it's going to end up in a Hobbesian "nature red in tooth and claw" when civilization starts to collapse, as it is doing now.
