Reading this it just occurred to me that the drop in concern over privacy has corresponded with the drop in shame as a governor of society's norms.
I use to work with Japanese national, we had a conversation once where he said that the US was a guilt based society and Japan was a shame based society. At the time I didn't think it was 100% true, there were instances where Americans are ashamed of their behavior. However, today I think the feeling of individual shame, in the US and the rest of the Western world, is probably at an all time low. People are less religious than they use to be, those who are religious seem to hand pick faiths that support their desired lifestyles. People also seek media that enforces their values as appose to getting the 'established' opinion on a topic as they would in the past.
I am old enough to remember when the average person had two or three skeletons in their closet, these days most people wear their choices on their sleeves.
