I am not a citizen of US but I will commend the president's gesture to wave the debt for the students. Although, the policy to loan student money to complete their school is not necessary in the first place and I assume it to end in this way. Nigerian government has replicate the policy as well which to begins in September. full details here.
The point is, what student need is a working system that their future will be assured after graduation. The government should allow students and their parents to struggle for school fees while government employs them after graduation and not the other way round of giving them loan that they can not be able to pay off after graduation due to lack of job. By offering the loan will just inflate the number of jobless graduates in the street.
Provide a working system and not loan that you will continue forgiving. It's obvious, you either forgive or you arrest countless number of debtors.
