Intolerance

As is usual, one thing lead to another while web surfing and I'm on the Wikipedia page for XIT Ranch.  It mentions that low cattle prices, rustlers and wolves helped lead to the ranch being unsuccessful and sold off after ~3 decades.  The article also mentions another ranch (J A) that is still successful after ~130 years.  Then the article shows the ranch rules:

The XIT Ranch had a number of rules including the following:

• No employee was allowed to carry any weapons for offense or self-defense.
• Gambling or card playing of any description was strictly prohibited.
• No liquor or intoxicating beverages were allowed to employees during their time of service.
• No employees were allowed to hunt wild game on any of the XIT horses.
• Employees were not allowed to own any of the horses or cattle on the ranch.

Which wolves were they talking about?  The WCTU?  Gun bigots?  Competition for employees?  Nope, couldn't see that failure coming.
