Cynicism has its place. But not as a tool to erode family tradition. Good luck in the Brave New World.Labor IS a commodity, like hog bellies. It is a unit. Like any other unit of production. Businesses opening on Thanksgiving, and they are opening at 8PM long after the family arguments have bored or antagonized the family members out the door aren't influencing family togetherness, it is a response to the lack of family togetherness.
What you are not quite understanding is that all family traditions are not YOUR family traditions. You said that your position is the Norman Rockwell, idealized family get together. Very few families are really like that. Today, more than ever fewer families are families in that traditional sense. There was a time when "tradition" did not include either television or football. Now it does. People have to work to make that football game happen, not least of which are the players themselves. How many men get tickets for the big game and leave families who can't be bothered at home?
Tradition is extremely personal. It is YOUR tradition, and yours alone. It is not shared.
Left brain, meet right brain. Yawn.
