When you are rich enough then a 7K vs 3K decision would be the equivalent of comparing $50 Levis 501 vs. $200 APC (my jeans knowledge is weak so that's what came to mind). Jeans is jeans and the rest is branding right? A lot of rich people (not all) don't sweat the small stuff.
yeah, maybe my mistake was trying to apply logic to rich people's purchasing decisions. It is their money to spend, after all, it doesn't make much of a difference to them, and like you said, many of them don't care. Personally, I was raised to take into account those details even if it wasn't a significant amount of money to me, so I'm probably guilty of projecting my own opinions onto the question and passing it off as objective knowledge. My bad.
