If you had researched this idea you would understand why it is a bad idea and why there is incentive to follow the traditional student loan route.
I listened to a finance podcast one day where the person (a dentist in this case) still had student loans which were quite substantial. But he was not concern about them because the system was as long as he paid his defined income based repayment each month for the term of the loans any remainder was forgiven. I do not know the details of who forgives or how they are set up, but I would imagine many people take advantage of some clause like this, which is not beneficial for the lender.
By sharing poor quality research, if researched at all, considering you state you heard it on a podcast somewhere and cannot even reference the source. All you are doing is hurting your brand with slapped together ideas that make no sense.
