I don't know about this thread.
This is a prime example of one in which I have some interest in responding and take a while to think of something to say. But then I really debate whether or not it is worth it because the accusations of KJVO, or fill in the blank start flying.
Also, gb, you kind of intimidate me with your posts. You sure sound like a my way or the highway kind of teacher. That if anybody has any troubles in your classes, it MUST be because of coddling parents, lack of motivation, laziness. Couldn't possibly be anything else such as a failure to clearly communicate on your part.
Or,

expecting too much. A kid that spends 7-8 hours a day at school and then 4-5 hours a night on homework is spending too much time on school work. There does need to be family time, church time, hobbies, exercise, sleep, goofing off. Maybe you don't mean 4-5 hours a night, but many who sound like you do mean that.
Anyway, my kids go to a great private Christian school. It is state-accredited. And I want state accreditation. When kids have to enter public school, there are big problems entering from a non-accredited school.
This school does not teach Greek. But it has taught Latin for a number of years for all the reasons mentioned plus more. One of my children did fine. Another really struggled. And no, it was not because he was lazy or we coddled him.
The pastor, I am sure, can make recommendations, but there is a school board, a budget to be met,college entrance standards to meet, and choices to be made. Finding a certified Greek teacher, at a price the school and parents could afford, would be a challenge.
This school has various Bible survey courses, Scripture memory, and missions endeavours.
If they were able to offer Greek as an elective, more power to the people that would want to take it, and I am sure it would help them. However, one should not assume others making a different choice were less spiritual or more lazy.
I would be more interested in seeing a church or group of churches offer Greek to interested adults and youth.
No, I am not KJVO remotely. Haven't even used a KJV in years. I like the ESV and NIV.
