Yeah, newer generations have been raised on tech that “just worked” consistently. They never had to do any deep troubleshooting, because they never encountered any major issues. They grew up in a world where the hard problems were already figured out, so they were insulated from a lot of the issues that allowed millennials to learn.
They never got a BSOD from a faulty USB driver. They never had to reinstall an OS after using Limewire to download “Linkin_Park-Numb.mp3.exe” on the family computer. Or hell, even if they did get tricked by a malicious download, the computer’s anti-virus automatically killed it before they were even able to open it. They never had to manually install OS updates. They never had to figure out how to get their sound card working with a new game. They never had to manually configure their network settings.
All of these things were chances for millennials to learn. But since the younger generations never encountered any issues, they never had to figure their own shit out.
In America, the reason is basically “religion”. There are architectural standards which designers refer to for guidance, and the dude who did the architectural standard for restrooms was super hardcore religious. His standard called for big gaps in all the seams, to prevent people from masturbating in the stalls. Basically, he wanted people to be able to peek into stalls, as a sort of modesty check. And eventually, it just became accepted as normal, even though everyone (including Americans who were born and raised with them as the standard) hates the huge gaps.
In modern day, they’re mostly done to deter drug use. I guess the reasoning is similar, with the large gaps intended to allow people to peek into the stalls and see if someone is doing drugs.
