Hundreds of kids got their hands lodged in Easy Bake Ovens, many got serious burns, and one child had part of a finger amputated. Hasbro still sells Easy Bake Ovens; they've just been redesigned so that your five year old doesn't have to be removed from it with a bone saw.
And kids 100 years ago lived handling guns from a young age and lived dangerously.
It gets worse the further back in time you go.
Aside from the stupid product that hurts people like 'The Cornballer', it's still stupid people doing and allowing stupid things that stops us all from having good things. All of society has to cater to the few stupid people every time.
Those were parent's fault for not teaching or supervising children.
We grew up with easy bake ovens, we knew the dangers. We also had the creepy crawler molds and ovens. We knew better than to eat playdoh, we knew not to ingest 'slime'. Yet still stupid people did it. Wasn't the product's fault.
More than 2,280 per year? At a cost of 12 child fatalities. [0]
And I'm aware of expanding electrical code requirements, every time I have to deal with a tamper-resistant outlet or AFCI over-exuberance with an unhappy motor. Or spill-proof gas can nozzles.
My point being -- there's a optimal balance between efficiency and safety, and it's not "zero accidents, ever."
And you quip, but getting a 120v pop as a kid certainly made me respect thoroughness in ensuring circuits and components are depowered before work and being extremely careful working on live wires.
Absent my "accident" I would not have had that caution, and the consequences working on subsequent higher-amp systems would have been more serious.
