The song isn't about materialism. It's just about overworking yourself for money. The person is only spending their time working and staying 'healthy,' which is where the expensive vitamin pills, wheat germ, and running shoes come in. The song points out that this is just an illusion. Though you may seem to be doing well to others, having a decent-paying job and your (physical) health, you're neglecting your self. Thus, you've become mentally ill, not on the same level as someone in an insane asylum. Nonetheless, with little time to yourself, you've basically become a robot.
