Not speculating as to the reason why mtmail is being downvoted, but for those wondering, the reason the nazi Yellow Badge comparison is almost always off-limits is because there's really only one hard and fast rule as to whether the comparison is valid:
Is an entity imposing an identification system for quickly singling out populations with invisible but immutable characteristics? If so, the Yellow Badge comparison is apt because that's exactly what the nazis did with their badging system.
Amazon identifying people within certain buckets of employment doesn't fit this comparison because opportunities exist (in theory) for people to take other roles, to quit, or to be terminated, making Amazon badges identifiers of a mutable characteristic.
Now, is badging people by employment class a crappy thing to do? Probably. Easy way to enable eyeballing a worker and denying certain perks, for instance. But it's also useful in determining whether a person is qualified to hear certain company-confidential information.

tl;dr: There's never a good reason to compel visible identification for an immutable trait, but that's also not what Amazon's badging scheme is, so using the comparison risks cheapening the original sin.
Hope this helps anyone reading. And to any historians who probably know better than I do, kindly fact-check me. I only know enough to be dangerous, not useful.
