Probably the same way they’d view the young tech startup billionaire. They’d understand they’re just seeing snapshots of an industry they don’t fully know so they’d avoid generalizing to “all young tech workers are billionaires”.

Why you’d think you can characterize an entire industry based on a few snapshots is not clear to me.

A few more things I’d add to the health risks of welding: the inevitable toxic crap on the hands even just by taking off the protective equipment, or the occasionally extremely uncomfortable body posture that needs to be maintained for hours on end while welding. And there are more extreme welding environments that put almost any job on earth to shame, like hyperbaric welding.

Over years things add up. If office work is hard on the body for too much sitting which is natural and fine is smaller doses, imagine work where even the small exposures are terribly bad.

Source: only welded once in my life but worked for a company that did a lot of it, from the mountain top to the bottom of the sea. All the safety avoids acute issues but the chronic ones will build up.
