They messed up and somehow built things to the total thickness spec and not the inside of the case specs it honestly sounds like.

Do you not know any wealthier people or are you just ignoring reality? The average person with money has it because they DON’T just throw it away all of the time willy-nilly on bullshit. They buy top-of-the-line once and expect it to last through servicing and repairs and such. I mean, there are truly over-the-top rich idiots and asshole exceptions to the rule but for the most part, what you’re describing is what I see almost every time a poorer friend of mine has come across an inheritance. I know one guy who has blown through 2 inheritances and an out-of-court car accident settlement pretending to be rich. He’s 39 and lives at home with his mother in Detroit now lol.
