Instead the argument is that the terms of the debt are not just or that people did not enter into the debt fully voluntarily (e.g. medical debt isn't much of a choice when the alternative is death/disability, student loan debt isn't much of a choice when low skilled positions don't pay a living wage).
The proposed solution generally takes the form of canceling existing debt, reforming future debt, and reforming society so that the debt is less necessary.
If you can vote, you can read contracts.
IMHO, we should raise voting age, precisely because of things like this. And because many entering these agreements today would be considered underage, more scrutiny would be expected.
But, until then, voting is a golden standard.
The problem is, while Astra Taylor may get that, I'm not sure that Biden does. I haven't noticed the "reforming society" part in the debt forgiveness proposals that have been floated.
(It's an NYT opinion piece, so straight into the garbage it goes, but it's written by Astra Taylor, who I value for her contributions to unschooling way back when, but since it's not free, I can't be bothered)
