The learner has to do most of the work, no matter how you structure the classroom. It's just a question of having them do productive work. Giving lectures and having students do problem sets at home still has the students doing a ton of work, but the instructor's expertise isn't utilized efficiently. By having students watch videos/do pre-reading and then work problems in class, the instructor can actually help people how they need it. You aren't paying someone to do the work for you. You're paying someone to structure the material in a way that helps you learn it. Think of it like you're paying a chef to prepare a meal that you have to chew. They aren't paid to baby-bird it to you. "Why is tuition so high" is a really contentious question. Not many of those dollars go to instructional staff (I assure you their salaries have not grown alongside tuition). Where has the extra money gone? Buildings, administration, athletics, who knows...
