In Saudi Arabia, women can't drive. How can a society be productive when half the population is effectively immobilized? Should fathers work a job and also be responsible for groceries and children's activities?
In rural Pakistan, small girls are betrothed while they are under the age of 10. How is a marriage supposed to be functional when there is no test for compatibility first? Is true love just a myth, like our cynical society would lead us to believe?
All over the middle east, women are discouraged from pursuing higher education. I wonder where they get their nurses, therapists, and elementary school teachers from? Oh well, at least the women can't fuck it up.
We can observe that Western society, which affords females more privileges, is more sustainable than the absolute patriarchy we observe in middle-eastern societies.
Are you trolling? Considering Saudi Arabia has a massive influence on the world at large, I would say their society is pretty productive.
If you think the primary point of getting married is to show how in love you are, you may as well write up a divorce letter now. Compatibility is not an innate value, that either exists or doesn't; it's a learned behavior. Considering that society's divorce rate is lower than ours, I'd say their marriages are more functional. Whether or not you agree with their concept of marriage is beside the point - you are trying to say it doesn't function, whereas it clearly does.
As to your third point, are you saying that the Middle East is absent of nurses, therapists, and schoolteachers? It's either that, which of course is nonsense, or you're instead saying that those societies suffer because men are doddering fools incapable of inserting an IV drip. That sounds more like "raising the lesser sex" than "making men and women equal" - which is an asinine proposal anyway, not only because it requires eliminating the very concepts of masculinity and femininity in the first place(and thereby showing its true nature, which is misogynistic), but also because it is literally impossible.
Finally, if Western society is indeed more sustainable than the absolute patriarchy that obviously intimidates you, there is no reason to believe that this is due to women being able to vote. In fact, the West experienced great successes prior to women being given positions of power. Women were given voting rights in the USA around, what, the mid-19th century? So that's about 150 years? Whereas absolute patriarchy has existed in the Middle East -hell, most of the world- in an uninterrupted state for... millenia. A proven system sounds more sustainable than an unproven one to me.
Reality is against you. Guess who wins.
