There was an interesting piece in the Opinion Journal (WSJ online) last Friday, discussing this very thing. The title of the piece is "The Decline of the Sabbath." The article is partly a review of A Day Apart by Christopher Ringwald.
A telling quote from the article: "Of all the gifts Jews gave the world, that of a weekly day of rest is certainly one to be cherished. And yet the Sabbath is now marked more by its neglect than its keeping." (emphasis mine).
Something to think about.
