Why? A farmer works hard to preserve his cows' health (every cow that gets sick is lost money), yet they are fungible units on their way to the meet grinder.
Sick cows don't always mean lost money, and farmers don't work hard to preserve the aspects of the cow's health that doesn't cost them money. For example, it's actually cheaper to keep cows in conditions that would cause any animal to suffer from depression, than to care for their mental health.
It may seem weird to talk about the mental health of beef cattle, but we're not talking about beef cattle, we're talking about workers, whose mental health absolutely does matter.
The two things are perfectly compatible.
