Why our education system sucks

Via reddit, I found this link to some kind of discussion forum. Here's the entire comment:

book rental service?

was just thinking. my sister does -alot- of reading, and spends like $1000 a year on just books alone. most of them she reads once then never looks at again. is there any kind of like ... video rental store but for books? would make things alot cheaper, plus once one person has read one the next person can get enjoyment from it etc
