From a different perspective

There is simply not enough food to supply the needs of an expanding population. The need for food is increasing and as a result, efficiency is the key to providing the food at the least cost. "Factory farming," as it is called, often derogatorily, provides food for people at a low cost. The low cost translates to a low price which surely helps lower income families. Meat is no longer a commodity to be enjoyed once a year as it was for the peasant of feudal Europe.
