The current social dynamic between men and women will last until our western societies collapse one by one into total social upheaval which I believe will occur within ten years or less. I say that because China is estimated to replace the United States fully by 2030 and when that happens all kinds of chaotic things will transpire around the world basically shaking our western societies to their very core in collapse for numerous reasons.
When that occurs should be very interesting, you'll have entire generations of privileged, entitled, pampered, and narcissistic women thrown onto the streets with a majority of men they've been shitting on nonstop the last 65 plus years, it's going to be an interesting new social dynamic amid the national or international chaos that is set to fall on us all. Women will find out pretty quickly in such an environment what it is like to be hated by a majority of men once all of that transpires. Again, best estimate and guess, ten years or less from now.
[Further note: It will be like a Soviet Union style collapse of the United States itself, that's what we're looking at here only it will be a thousand times worse than it ever was for Russia.]
