Where I live, ground chuck goes for $4/lb, and chicken breasts go for $7/lb. Not sure what the cost per pound of an entire steer versus an entire chicken, but I don't see the same price variance that you're writing about.
Also, the ecological impact might be because Crappy Factory A is manufacturing cheap shovels and dumping their toxic waste in a local river, while Factory B has to charge more because it's following industry standards and using a reputable waste handler.
Or Crappy Factory A might be using underage employees, or dumping product to eliminate its competition.
Drawing conclusions about manufacturers based on pricing is dangerous.
