Student Loans - when will they ever end??

How is it that I am still paying off my student loans?

I graduated from undergrad (highest education achieved) in 2012. I am now 35 years old and my Nelnet still shows 8 payments on loan group A and 9 payments on loan group B. (I paid off group C loan a couple years back somehow)

Mind you, my first year of college (Temple U) was fully paid for as my grandfather had money saved from his pension which was used for that (I don't take for granted how fortunate I was to have that). I then transferred to a SUNY college (I am from NYC) as I knew I'd be paying the rest of my loans off on my own and figured I could save a lot of money by getting an equally good education from an in-state school.

Granted, I've only ever had payments of about $100/month since I took out the original loans.

Is it just me or are student loans the most predatory practice in this country? (besides medical insurance but let's not go there!)
