> 1:1 classroom instruction removes a number of teachers from the labor pool equal to the number of students.
It does require more teachers, but not 1:1. Students being taught 1:1 learn a lot faster, and can be set work to do unsupervised. From my experience I think less than an hour a seek (sometimes a lot less) of tuition time (plus a bit more for marking, and another few hours of study by the student) is sufficient to cover a subject 1:1 (and it can often me a lot less) for teenagers (specifically for GCSEs - British exams sat in schools at 16).
it does require a significantly higher ratio than classroom teaching usually does, but its a long way from needing 1:1.
