“Notably, Chang’s report claims that biological females develop earlier than males do, so requiring girls to enter school at younger ages will create classes in which the two sexes are of more equal maturity as they age. This, the author posits, makes it more likely that those classmates will be attracted to each other, and marry and have children further down the line.”

“The report does not include evidence of any correlation between female students’ early enrollment and the success rate of their romantic relationships with men. The author also does not detail specific mechanisms by which his proposed policy would increase romantic attraction or birthrates.”
All it really amounts to is a small headstart. It seems like a big gap initially because you’re comparing 0 years of experience vs 2 years of experience.
But across a 30 year career its a mere 7% difference. Frankly after 5 to 10 years of experience it becomes a lot less about how long you’ve worked, it instead becomes more about how you’ve spent those years and how that translates into benefitting the company. When a company is hiring for mid level and above, it doesn’t really matter to them that someone has 8 years vs 10 years. An extreme example would be someone with 5 years at Google vs someone who spent 10 years jumping between small start ups.
