Of course Jesus understood the plight of women.  That doesn't mean the plight of women was his reason for forbidding divorce.  In fact, while knowing the plight of women, Jesus excluded that as a reason for prohibiting divorce.  Indeed, the plight of women could not have been the reason for the proscription, because there were surely women who wanted to, and could, divorce destitute husbands and marry up.  Jesus forbad this as well.  So, once and for all, please clear the table of the dirty dish that Jesus's proscription against divorce was only intended to protect dependent women, and that since women are no longer dependent on men, Jesus's rule should fall by the wayside.  That's simply not tenable.
