This is about the Khasi in India, one of the few matriarchal societies. There isn't much coverage, but I have added links to articles. Looking at this article, is this where we can expect society to migrate to in circa 50 years? I don't think it would be this extreme, but the attitude of the woman towards the men is telling. I'd be very interested to hear from men in India on this topic as well.

'Mr Pariat said: “When a man has to live in his mother-in-law’s house, it tends to make him a little quiet. You are just a breeding bull. No one is interested in hearing your views about anything, you have no say in any decision whatsoever.”

He believes that the matrilineal culture has been “totally detrimental” to Khasi men, saying: “It puts no responsibility on their shoulders so they tend to take life easy and they go into drugs and alcohol and that cuts their life short.”'
