All the reasons you mentioned plus the fact that those who can get a decent wife are in a condition which allows them to pump and dump attractive girls with no obligation while those who cant pump and dump decent girls fail to attract women.
Right now women are getting what they asked for, top dogs getting all the rewards and the majority getting nothing, pity for them that in this process they get screwed up as well.
I see myself no reason to get married in the short term, given different circumstances (culture and law) I would plan to do it honestly but simply because Im reaching the point where sex doesnt motivate me as before and one single decent girl wouldo so...also to have a family and some intimacy.
But in the current situation I realized its not gonna happen.
Right now if you have what it takes to marry properly, you can still own the field while you cant own the field, you lack what it takes to get a good deal.
PS. fvck society, whatever you offer, I can do better by myself in terms of economy or private life, the deal is not worth and I choose my money and freedom over your taxes and crappy welfare.
