I don't think it's negative, but it's quite marginal. As noted above, in most traditional civilizations, upwards of 90% of the population was engaged just in growing food, generally as unfree labor. The remaining 10% were priests, nobles, and soldiers to keep the peasants in line and working hard. Such societies typically also had famines every few years. We don't have famines in developed countries any more.
