I recommend all of these:
"Restrepo", "Tapped", "Food Inc.", and "Capitalism a Love Story"
In Capitalism a Love Story Michael Moore asks the same question to three different priests that has been haunting me: "Is capitalism a sin?". All three of these priests responded with a fervent YES that capitalism is inherently sinful and evil.
This is something that I have pondered before and am still wrestling with in my mind to figure out. There will be more about this question later because I have drawn no conclusions, have really only wrestled with this in my own mind, and I want to have more conversations with people way wiser than I before I draw conclusions.
