Vegetarian, Vegan and Animal Rights

There's no profit in reducing suffering. They're too busy speeding up the line and reducing labor costs to take the time to do so at all effectively, and sometimes they have unsupported notions that doing so is harmful to the slaughter process. Chickens often don't get their necks cut by blades on the line well enough to bleed out before being dipped in scald tanks, cattle facilities often turn down the pressure on captive bolt guns because they believe rendering the animal "too dead" reduces the quality of the resulting meat, pigs often go into scald tanks alive as well, etc.
