There are two different issues addressed: patriarchy and capitalism.
Capitalism is the reason why so many men are failing (it was mentioned before, homelessness, education, drug addiction, college and university drop outs …). Women are doing better in these areas because most of them have better networks and more friends, they are simply better in socialising.
Capitalism leads inevitably to a small group of wealthy people financed by most of the people. Men have a harder time to deal with not being part of the wealthy group.
Patriarchy promises men that they are better than women, they deserve more and better options than women.
The structure of capitalism was shaped by patriarchy, that’s true.
Why do you think women’s rights are taken away more and more? It’s because women are doing better in capitalism than men. Sure, they never get to the top positions because of patriarchy, but in general they are doing better in this system.
