I think it's great that Biden is doing this.
It's really sad that his relief only extends to undergrad. This is, after all, INCOME-BASED help. If people with graduate degrees are struggling with low income they are, by definition, in just as much trouble. Probably more trouble since their loans were more expensive.
While Biden isn't going far enough, at least he's doing something.
Contrast that to Republicans, who, out of pure cruelty, tried to add RETROACTIVE interest to student borrowers.
