I won't disagree with the "men have it hard" crowd but as a man myself my observation of the root cause is complacency. Blame "male privilege" or "men rights don't exist" or whatever but I have not seen this problem in poor countries or in immigrants from poor countries.

i.e.: in the US at least you can get just enough to be complacent as a man by doing bare minimum stuff.

So why endure hostile environments, places where you don't feel like you belong, etc... when the benefit is "you can afford just a little more stuff", especially when you are not planning for long term success.

Contrast this with east asia or india where you have the other end of the extreme where mostly men kill themselves when they get bad grades or fail standardized tests because it means they can't get any job that matters or pays well and subsequently lose social perks like getting married.
