How Many agree to this?

Business leaders who adopt the attitude that anyone is replaceable, thinking they can simply hire someone with a greater skillset or someone with a more prestigious pedigree, are fooling themselves. When a company has a truly great employee, that employee carries value that simply cannot be replaced. They have extensive product, systems, and process knowledge. They hold client relationships that have been built over many years or could take years to duplicate. And great employees have camaraderie and influence with their coworkers, which when lost, has an impact on the corporate/company's culture within. Do you agree?
