Thanks for committing until the end, Death Toll!
Maybe I'm on the minority but I found the ending horrifying. All their children (assuming they don't die due to childbirth complications) are going to grow up and be iliterate. I wonder If at one point they will realize their kid is missing out on a lot of stuff parents want them to experience (school life, having friends etc) and then will finally go back to society??? Unlikely but yikes. The future looks grim and greasy for these folks.
