Teachers are workers, underpaid teachers are mediocre workers and the result is mediocre teaching skills.

Now, being six hours straight on a torture chamber seating on a medieval torture device are not the best conditions for learning.

I remember in the nineties I went to Japan for a course and they had executive chairs for every student, a nice desk, two whiteboards for projecting slides, breaks every hour, bombarded with visuals it was the best learning experience ever, you never got bored.

And learning Japanese role playing different characters, that's how you learn a language for daily use. A student played as a cab driver, turned the seat around, and another in the back seat, asking to go to the airport, the academy, a restaurant, counting money in Japanese, paying, being thankful for everything. Unforgettable learning experience.
