Yes, that happens. It also happens w/ mortgages and other loans not associated w/ student loans.
My point was, if one is responsible enough to take out a loan then one ought to be responsible to keep track of it, and keep up with the status of it as time goes on. Can it be a new or daunting process if one hasn't gone thru it before and/or isn't familiar with the process? sure! That's why it behooves them even more so to be aware of their responsibilities with this debt. Not being aware, not knowing, head in sand is no way to go thru life. Can individual people get caught up with a snafu now and again? Yes, but in general the group of people with these loans can't just claim " no one told us" or "but we didn't know" or "I wasn't paying attention, I thought someone would tell me" isn't going to cut it in life in general in my opinion.
Of course, others will have different opinions.
And of course, there will be young folks who get fouled up somehow with this, and if they do perhaps going forward they should make it a habit to be more aware of the responsibilities that they took on.
