The answer is that we cannot and will not 'fix' them; because they are not the kind of thing that can be fixed (especially not by 'fixing').
The relations between men and women are the second most important kind of thing in all of reality (when we include with marriage the properly-linked matter of family); but they aren't the most important thing.
And the second most important thing cannot be fixed while the most important thing remains not just broken, but smashed; while there is no insight as to the absolute and primary necessity of fixing the most important thing.
It could be argued that we could, at least, stop making things worse between men and women - could at least stop actively sabotaging the situation, and pushing 'solutions' that actually exacerbate the problems...
But we would need to take a step back and recognise that the reason that we have an inverted, and opposite-of-reality understanding of men and women is because the most important thing is wrong.
While that most important thing remains absent, wrong, incoherent - where would we, where could we possibly, get the desire and judgement necessary to stop doing wrong things and start doing right things?
To suppose that we can (to any significant degree) 'fix' the relationships between men and women in modern life, or even to improve them overall, by changes to laws and regulations and social conventions - is itself itself a part of the problem!
Anyone who claims to know how to fix, or even significantly to improve, the relationships between men and women by changing The System is in fact on the side of the enemy.
(The System is built on on coherent, evil motivated dishonesty. The System cannot be made to do Good. Obedience to The System is intrinsically evil.)
Until we can understand that fact, and until we fix that problem; we cannot do anything other than continue to make things worse in the relations between men and women, and everything else.
