It also makes sense to me that adolescence is extended due to economic necessity not because men don't have to grow up to get laid anymore.
I sometimes like to have sex with alphas but I never wanted to have a relationship with one. Women are now free to make the same distinction between who they want to have sex with and who they want to have a lasting relationship as been have always had.that's not implausible at all. Women are attracted to alpha's, after all. Men therefore seek success not least because it increases their attractiveness to women, and their ability to turn that attraction into what they are seeking (sex). Give a guy sex without making him work for it, and he's like the butterfly you helped out of the cocoon. Happy now, and he'll never fly under his own power.
Your position implies that women always want commitment and men always just want sex. I give both genders more room than that.
