For the consumer therefore it matters what the actual value of the thing they bought for $30k is.

Will it lead to a $150K job, or a $80K job?

Will not doing it lead to a $80K job?

For the company, what risk do they have if most students will earn over 50K regardless of the quality of their product?

I'm not good at economics, but I think one can look at this deal from both the consumer and the provider and see that there are flaws from both sides. Trust is key.
