Into The Abyss is a death row documentary. It's about White Trash Americans who never had a chance to really escape the superficiality of a life where stealing a car for a day or so is the most braggable value they can achieve.
Capitalism needs a layer of society like this to recruit for their wars. If they have no interest in dying for rich men abroad then there's little else for them except to use as prison bait, so richer folks can always have something to demand more security and greater victimisation of poor people. It's very profitable to exploit fear.
There are truly touching moments in this documentary. It's a view of America that isn't shown by Hollywood which focuses on programming people to aspire to superficiality.
