You've hit the nail on the head brother. Everyone goes to work, comes home, the family divides and goes to their own little cubicles to sit on computers & play fantasy games. Families don't eat together, work, hunt & fish together etc..
The USA has never seen violence, death or war except on TV (for the most part!). Every word must be weighed in advance for fear of violating the rules of political correctness.
Disconnected or disassociated due to technology, along with other reasons you've stated like the break-up of the core family unit and more - which I won't get on a soapbox about are IMHO setting us up for the worst possibilities in worst case scenarios.
