 Gutman challenged this argument, as Fogel and Engerman seemed to ignore the fact that slave’s spouses were not always sold to the same master.Furthermore, the authors of "Time on the Cross" did not take into account the friends and extended family of slaves left behind, again ignoring the disruptive impact this had on slave families and communities.In "Slavery and the Numbers Game", Gutman argued that Fogel and Engerman chose their examples poorly, focussing on plantations which were unreflective of broader southern society.
