Eric Siu argues that waiting until 30 to settle down puts women at a disadvantage. Around that age, he says, the sexual and romantic marketplace shifts so men's value surpasses women's, making it harder for women to secure relationships on their terms.
The game of mating and dating shifts significantly at age 30. Age 30 is basically when the average man's sexual marketplace value exceeds the average woman's sexual marketplace value for the very first time, and it will never reverse after that point. So in their 20s, women enjoy a relative advantage in the game of mating and dating, and that advantage comes with certain privileges that, if they're exploited, make it easier to secure relationships on their terms. But if they wait until after 30, when the balance of power kind of shifts, they find that it might be surprisingly difficult to secure relationships on their terms. Now that the men become increasingly powerful after that point, they are able to more secure relationships on their terms.
