You can argue all you want that it SHOULD be enough to share lifetime costs, but it doesn’t work. Just look at people who still buy incandescent light bulbs because they are cheaper at the cash register, even though they will save a multiple of the cost of the bulb over its lifetime.
We as consumers seem to ignore or discount future pain for lower prices now, which is why operating costs are ignored by average consumer if they mean higher upfront costs. And when marketers try to bring future savings into the present and get you thinking in terms of total cost of ownership, even the rational-types at HN cry "dark pattern!"
All of this is to say we haven't yet found how to make "it's cheaper to live in" an effective message.
Solar folks are getting there, though ("the system pays for itself in 5-7 years"), and with the rise of EV's, I think this reasoning will become more common.
The "dark pattern" complaint is that actual realized savings (tax credits) are mixed with hypothetical savings (future cost of gasoline) and taken off of the sales price. Meanwhile, things like delivery fees, sales taxes and maintenance cost differences are not added back in.
It's one part standard marketing, one part underhanded marketing imho.

That's because it is fundamentally inaccurate, and therefor counter-productive. I'm all for demonstrating TCO differences, but when you show a "price" of $26k and the actual price is over $40k with taxes and everything added back in, suddenly you get struck with a bit of cognative dissonance.
