It all depends on who has the deepest pockets. Mpm and Pop shopkeepers have limited pockets- insurance coverage, etc. Major multinational corporations have more business liability coverage, not to mention cash reserves.
To wit: Ford Motor Company and the Pinto.
It would have cost Ford a minimal amount to recall and retrofit the Pinto with a protected bolt, a plate to protect the gas tank behind the bumper, and re-route the tail light wiring. Their accoutants decided that it would cost more for the recall than any possible legal settlements incurred in accidental fires resulting from read-end collisions.
Hence, we have the famous Exploding Pinto.
It's all about the Benjamins.
