>She can have access to a big chunk of all the songs ever recorded, on-demand and for FREE (ad-supported Spotify).
Which she could afford to pay for (albeit at a much lower price than the cassettes would have commanded, appropriate for the advances in distribution efficiency) in a parallel today.
>Similarly, the used car she buys now is leagues better than the one she'd buy back then; not just for her, but environmentally and in terms of safety.
But it's not anywhere near what a new car offers in terms of fuel efficiency and especially safety. So there is a relative QoL loss there.
>The cost of education is a real shift. But if these are the best examples you can think of to extend that to describing the average family as having "declining standards", you're proving the exact opposite point.
They're not, they're just the first that came to mind that fit in a neat illustration.
The overall point is that we're no longer capable of paying outright for things we used to be able to. We have to rely on workarounds (ad support, used goods, debt, theft) to maintain a semblance of the same QoL. Our standards haven't declined perceptionally because we have those tools, but their use is anywhere from unsustainable to morally-objectionable. And if you take them away, you have a far poorer American than one or two generations ago.
