Men are generally more willing to hook up with women below their sexual market value (SMV). This creates an imbalance in supply and demand - therefore women generally have more potential suitors than men.

Before dating apps existed, this imbalance was less critical because dating was more localized. You were more likely to date or hook up with someone in proximity - a coworker, friend, classmate, etc. Spending time around the same people was a bigger factor than today. The imbalance between supply and demand didn't matter because the market was less efficient.

Nowadays, all modern dating is mediated by extremely efficient algorithms like Tinder. Any small imbalances between supply and demand are exacerbated. An average woman who used to receive only a few opportunities now has access to hundreds.

This happens due to pure economics. The market simply shifts because there are more “sellers” and fewer “buyers”. Online dating has expanded the dating market, and therefore there are proportionally more men offering than women taking. The effect scales with the population of the city you live in. The larger your nearby dating pool, the more dramatic this effect becomes as you compete with more people.

Factors like in-person proximity and relationship market value (RMV is much more even than SMV) are weighted less on these apps, and SMV is weighted much more. And it’s all made worse by the recent mass social isolation.

The inevitable result is that the top men receive almost all the attention while the rest are largely ignored. Meanwhile, women are flooded with sexual opportunities and fewer long-term prospects.

Hypergamy is the result of basic economics. This happens without the need for redpill conspiracy/bluepull pandering.
