We'd only display a few "standard" stainless plated printer cables, and flood the aisle with gold plated Belkin cables, costing over $40.
Is the connectivity even remotely better with a gold plated cable? Is there ANY benefit besides lightening your wallet the gold cables provide?

EXACTLY. Even the cheaper cables are gold-plated where it really counts - the actual contact fingers. The biggest differentiation that I see in printer cables, is the gauge of wire used, and the amount of shielding. I've seen longer cables that are poorly-shielded become the victims of nearby interference, likely due to unshielded AC cables nearby. Nothing like print jobs getting randomly garbled in the middle. Likewise, there are some minor differences in wiring between straight-through, bi-dir, and IEEE-1284 cables. The last one being comprised of a number of twisted-pair connections, like ethernet cables.Originally posted by: Phil
4. The Belkin rep told us that the connections in the regular cables are gold-plated anyway, so there's no need for these things but they make them a lot of money.
Completely pointless.
Actually, you have that backwards. At some level, even "digital" signals are transmitted in analog. Square waveforms can easily get distorted along the way between transmitter and reciever, such that they don't seem so square anymore. Likewise, if there are stubs or dissimilar-enough impedance in the cables, that there can be waveform reflections that get mistaken for the original signal, and if the cable is too long and there is too much loss, the waveforms can get attenuated so much that the digital recievers on the other end don't properly pick up the signal.Originally posted by: DukeN
For data being sent, it doesn't really matter since it doesn't get distorted or 'lost' like an analog audio stream might, for which the cable type may make a difference. At best you may get a neglegible speed improvement.

But note that gold-plating itself doesn't really have anything to do with those issues. Also, there is no difference in signalling speeds caused by different-quality cables, although poor-quality cables that suffer from transmission problems due to the above issues, can cause drops in throughput. Perhaps that's what you meant.
The rest of your post is all completely true.
