Who is the richest cowboy in America?

Can you enlighten me on the identity of the wealthiest cowboy in the United States? I'm genuinely curious to know who this individual is, considering the diverse and vibrant culture of cowboys within the country. Are they a renowned rancher, a successful cattle breeder, or perhaps an entrepreneur who has capitalized on the cowboy lifestyle in some unique way? I'm eager to learn more about their accomplishments and how they've accumulated such significant wealth within the cowboy community.
