My dad fixed up a Chinese laser cutter to save money (it was like 1k by the end of it), it sat in the basement for a while there. Personally, I assume YT is not their only job. I’ve worked with people that have sunk way more than 10k into their hobbies, the car people in particular are sometimes unbelievable and that I don’t get. Drone and boat people too. The small planes are kind of cool. At least with these tools, you can actually make money off them.
I’ve definitely had people who were working for me say “I have four boats” and I’m like wtf bc I know how much they make. Then I find out they live over an hour away from work in the middle of nowhere, their mortgage is less than half my rent and two of the boats are “project” boats that don’t even run. The only drone person I know is childfree, huge savings right there, and they don’t live in a city either. Tbh some of the things people do for these things, the amount of work does not make sense to me but if that’s what you want to do with every single weekend, go right ahead.
Plus I find these people with a lot of money invested in their hobbies tend to be older, like 30-40 years old. Then I’m like, I could probably afford a 5k 3d printer in a decade but that’s not what I would spend my money on.
