There are countries that have practiced female infanticide for centuries (an act that has started to embrace technology in the form of gender-selective abortions.) Historically, when the number of available females has dropped significantly below the number of males seeking wives, bad things happen.
In the US, it has always been considered important for women to find husbands who can actually support a family ... even if the woman intends to work, the goal of acquiring a husband who _could_ provide sole support remains. That holds true despite the degree of gender equality we pretend to have embraced (perhaps because it's mitigated by the amount of misandry we've also embraced.) In modern society, that means an educated man. But we're rapidly eliminating the critter. I wonder what will happen when the future generations of girls grow up and find few viable husbands.
Perhaps seek out husbands in India and China, where the men can't find wives?
Or something quite a bit less civilized?
