$3.5k is a lot of money, but not a ton by American hobby standards. It's easy to spend multiples, even orders of magnitude more than that on hobbies like fishing, wine, sports tickets, concerts, scuba, travel, being a foodie, golf, marathons, collectibles, etc.
It's out of reach for lots of people, even in developed countries. But it's easily within reach for loads of people that care more about computing than other stuff.
In June 1977, the base Apple II model with 4 KB of RAM was $1,298 (equivalent to about $6,900 in 2025), and with the maximum 48 KB of RAM it was $2,638 (equivalent to about $14,000 in 2025).

I live in America, I am very well compensated. Have been for 15 years now. $3500 is a lot of money. A lot. There is a tiny bubble of us tech folks who think it is accessible to most people. It is not. It is also the same reason Macs are still a niche. Don't take your circles to be the standard, it is very very far from it, especially if you think $3500 is not a lot of money.
It is easy to confirm this, just look at the sales number of these $3500 devices. It is definitely not an enthusiast price point, even in the US.
I'd argue that some of those are more consumption and activity than hobby depending on how they're engaged with, and that people use the word "hobby" too loosely, but would agree that Americans in-particular consume at obscene rates.
Golf equipment, mountaineering equipment, skiing and snowboarding lift tickets and gear, a single excessive graphics card that's only used for increasing frame rates marginally, or basically a single extra feature on a car, are all things that accumulate quite quickly. Some are clearly more superfluous than others and cater to whales, while some are just expensive by nature and aren't attempting to be anything else
