It's not that they are good. It's that younger generations didn't learn fixing shit and spent time doing other things.
First of all, most fixes aren't that hard. Just think about it, what kind of people end up doing physical labor, operating heavy machinery etc? No idea how it's in US, but here in Europe it's usually guys who didn't do shit in school, their education path was random or of least resistance. People who had trouble with math, writing etc. And yet they can do these jobs. That's because they actually aren't that hard. I've made excavator licence just because there was occassion to do it for nearly free and turns out it drives just like a car, and operating spoon is like playing with joystick so you quickly catch up. Course was supposed to have like 40 hours of practical lessons with operating machinery, all of us in the group got like 1 hour each and most of us passed. Another example is removing rust from car. I actually tried because it just so happened I bought new car and had old one to spare so I could use it as learning prop. Obviously first time ended up shitty, but I learned a lot and it turns out you don't need to pay couple grand for someone else to fix this kind of shit.
Younger generations didn't learn it because we were busy playing games while older generations didn't have this potent time and attention sinks. Also our tech is often miniature electronics while theirs was much more simple and thus easier to fix yourself with just screwdriver and hammer instead of microscope. Also meme belief in education and pushing us to often waste time in universities on meme courses so we would avoid working physical labor, basically rat race with no one realizing that not everyone can be manager and white collar because you need actual dirty labor done as well. And they didn't pass these skills because natural intergenerational relations got fucked and barely anyone gets decent upbringing for decades already.
New gens are better at using tech
