He isn't denying that people are loyal to companies. He's just arguing that it's misplaced.

You probably don't want to know what I think of patriotism, most people find my views on the subject to be offensive.

But I never said loyalty to abstract entities didn't exist, the implication is that it's horribly misguided.

Sorry then. I misunderstood you.

But then why is that loyalty misguided?

How does it particularly different from loyalty to people (which you seem to think isn't misguided)?

Employee-company relationships are strictly business: service for compensation (usually $). Loyalty here is artificial because at any point the contract is breached (service declines, compensation is inadequate) the relationship is terminated. A business cannot choose to remain loyal to an employee if it means bankruptcy.

Relationships between people rely on more flexible rules: networking, camaraderie, common ground. A psychologist would say that these are a trade of "services" of a sort, but since nothing is inked, loyalty plays a stronger role. Unlike a business, it is not unheard of that a person sacrifice their welfare/life for their spouse/offspring.

It is misguided to expect the type of loyalty in the latter in the context of the former.
