I just read the letter in it's entirety. You can definitely tell he was an engineer. His frustration stemmed from chasing the 'American Dream' instead of just being a content drone in a cube, a cog in the machine. He wrote of many of the injustices of the American Way. Ones that we're all aware of, ones we complain about ourselves, but are too selfish or apathetic to do anything about. Joe did, in a dramatic fashion. After reading his manifesto, I can empathize with him. I give him an 'A' for his message, but an 'F' for the delivery.
