like 42, I don't see the workoholism and the porn addiction as very distinct. It's my observation (and this is held up by most books/doctors I've referred to in learning about addiction) that when a person or society suffers from multiple addictions, the two are not unrelated. Any addiction, be it chemical, emotional, or behavioral, is quite likely to manifest in or cause other addictions as well. This is why it's hard to cure someone of addiction by simply removing their addictive substance/behavior/whatever. The dependency and addictive tendency is still there and they haven't been taught how to deal with it. Thus they will either become addicted to soemthing else, return to the old addiction as soon as it is available again, or, most likely, both.
We have an addictive culture growing in the US, too, I agree. Alcohol, caffeine, tobacco, Internet usage, eating disorders, sexual addition (like porn) are all growing rapidly and they cause many more problems than the general public will usually acknowledge. Mormons on teh board will recognize yet another logical reason for commandments like the Word of Wisdom. Any person of a tradition of even quasi-"straight edge" behaviors (Christians, Muslims, Jews, certain other philosophies and cultures) will realize yet another reason why those standards are justified.
