I agree, which is why I support the complete abolition of teachers' unions, and abolishing school districts. Schools should have to compete for students just as businesses have to compete for customers.
But there is another reason why I support an optional extension to high school and that is dating. Since graduating from high school, even meeting young women I find attractive has been quite difficult. I'm 24, and the only girls I ever encounter who seem even remotely interested in me are middle schoolers.
The only girl I met at the college I went to who seemed vaguely interested in me was a chubby Latina... not my type.
On dating apps like Tinder, I only started getting likes when I changed my location to Norway... take that as you will.
After I left the college, I was hired at a Godiva chocolate store in the mall near where I live. In the 2 years that I worked there I only met one girl I found attractive and could've potentially started a relationship with - a 19-year-old girl who worked with us for about a month and a half until Covid shut down the mall. She never returned to our store after the mall reopened and I haven't seen her at all. None of the other female coworkers I've worked with even fall within the demographic of women I would date.
Just before I met that girl, I even tried messaging a cute transgender girl I came across on Snapchat, and not even she was interested.
I'm not really much of a drinker, and I've never been to a bar or club (I have Crohn's disease).
And as I recall, the only church I found in my county that had an ongoing singles group aimed at people around my age is Mormon, and I don't believe in that faith.
Overall, I feel like the best place to meet young women (at least where I live) was actually back in high school. If high school had lasted a couple years longer, I might have had better successes with dating - at least there, I was exposed to a high volume of attractive girls on a daily basis.
