Strictly speaking, the "disdain" for a woman who can't find a partner is part of the culture to the point that we've essentially normalized it and don't see it as an issue. Otherwise why would one of the first questions to a working woman usually be "So when are you going to have kids?", implying that a woman's only worth is in her ability to perpetuate the species... I would be willing to bet every single woman I work with who is not in a committed relationship gets asked about it at least once a year
