The social condition of the Kranks is quite a good one. They are well respected. This is seen in how they have so many plans to alter when they decide to skip Christmas. Social events and obligations, parties, and other similar reflections of high social status are what makes the Krank decision so critical. This status is also evident in how Blair can volunteer for the Peace Corps. It seems unlikely that she would be doing that if the Kranks were either economically challenged or socially maligned. Luther works as an accountant and makes enough for the family so that the cruise can be embraced as a possible substitution of skipping Christmas. Nora's Christmas traditions involve donating to charity and other social organizations, reflective of high social status.
The Kranks live in an affluent area. Hemlock Street is not poor. The neighborhood is filled with traditions of the holidays that reflect a solid level of status and prestige. The holiday party on the block and the entire street conspiring to make the Kranks feel bad about the Christmas boycott are reflective of a social status that does not experience marginalization. The social condition of the Krank family is one of acceptance and solid status. Grisham's work functions in this type of social condition.
