They are unhappy because:
1. Chad won't commit.
2. Normies don't give her butterflies.
3. Incels pollute her visual field.
Thanks to birth control and sex lib, the typical foid now wastes at least 20 years of their prime years collecting STDs and frying their dopamine and oxytocin receptors with drugs and promiscuity before settling down with a stupid cuck they'll never respect, instead of marrying, virgin, between 16 and 18 years of age to a loving husband and making a loving family.
Everybody knows what makes foids happy, it's not rocket science. As a domestic animal, a foid is much easier to please than a hamster or a fish. It is just (((our culture))) that is geared towards exploiting their unhappiness for (((profit))) just because foids are so easy to dupe and control, they're the low hanging fruit of marketing and social engineering.
