I can almost guarantee that everyone mentioned in that blog post is a habitual Amazon user. They're all renewing Prime each year at full price and making a ton of regular purchases. The family has even turned on the FOMO by making Prime a family social network with social pressure to stay. I see it as a self-own, personally.
Edit: I'm taking part of this to the root of the thread
E.g. an Amazon van rolls through my street multiple times a day. What is the marginal cost of them stopping at my house and dropping off a potato?
At my house, it's a 140 mile round trip between the fulfillment center ("are you feeling fulfilled yet?") and the drop off location.
OTOH, there's likely more of "you" than there are of "me" ...
While Amazon is efficient, "fractions of a cent" is probably the wrong order of magnitude for even the most efficient order.
It's the difference in 1990s billionaires and 2020s billionaires. Bill Gates was so rich because he owned a lot of Microsoft shares and received profits from those shares as dividends. Jeff Bezos is so rich because he owns a lot of Amazon shares and people keep being willing to pay more and more for those shares so his notional net worth increases (AMZN has never paid a dividend).
But that’s exactly the loophole: you can borrow for very cheap against this notional equity without incurring a cent in taxes (since divodends are never paid out)
At the very least they should charge more for bulk mail, not give out discounts.
The USPS is a government-run spam delivery service that there is no way to opt out of. Those of us who do banking and other administrative tasks online would be better off if the government shut it down completely, or better yet subsidized it slightly so it doesn't have to deliver spam to survive.
But as it is, I don't see any good reason to have any more respect for USPS than I do for any other spammer.
On the other hand, spam delivery is the business model of USPS. They actively and intentionally market and sell their services to spammers, and not surprisingly, give normal users no way to opt out.
[0] E.g. https://www.usglobalmail.com/virtual-mailbox/Alternately, you can forward your mail to an entirely different address. (This is just a Gedankenexperiment; please don't spam strangers by forwarding your mail to them.)
I was shocked when I moved to SF and found out there was no way to opt out of unaddressed mail (or "current resident").
