[We] had the exact conversation about the McRib this morning. We believe McDonalds is bringing back the McRib because it is a cheaper meat product (just a press of processed meat trimmings) rather than the more expensive bacon. Bacon this summer reached historic highs and, if you noticed, bacon has become a part of everything (salads, burgers, etc.). "So, in order for McDonalds to break even on their products they either had the choice of increasing the prices on their menu (an unappealing move for a fast food chain that might end up driving away more business rather than earn more revenue) or push a food item that has lower costs to produce: the McRib.
