That's an interesting fact in it's self. From people I know who teach or have taught, it seemed that they had too much to do outside the core hours, so maybe they are trying to get some of that time back?
That was to be my last point in the discussion, which ended 11 hours before your post.
I get it now, people will pay their own money to help their career, it's technically B2C but if they didn't have that job, they wouldn't buy the product. Most B2C products are independent of the customer's career, but this type of product is not. Similar products would be suits, some networking events, travel costs, smart shoes, working lunches, coffee, smartphones etc.
