It is a private USA business. I seem to remember you live in Europe? In the USA we have "at will" labor laws so the employees can leave and find another job, or the employer can fire the employee, at any time. There is no corruption in an "at will" employment situation. I think you are confused. This is a single individual, privately owned USA corporation which is an "at will" employer. Maybe you do not understand that? Your claim of nepotism is completely errant, but maybe unintentionally. Private companies in the USA commonly employee family members of the owner and managers, it is very common. It is not nepotism. I assume since it is not nepotism, but you claim it is nepotism, that you have an agenda, but maybe you do not understand. You might not agree with the legal basis, but that is the system in the USA, and accordingly nepotism is not involved in hiring family members of the owner or management. Jonathan Kraft is an employee, and that is not nepotism. It is not a matter of me being fine with it, it does not exist.
You can say the Robert Kraft is instinctively biased towards his son, Jonathan, and I agree. But that is not nepotism in a private USA corporation. Yes, I agree the biggest reason that Jonathan Kraft is the president of the New England Patriots is because his Dad, Robert Kraft, owns the team. This is true. So what? That bothers you?
