I forgot the name of the cognitive bias, but this thread reminded me of something.
As others have mentioned, for every "LV quality is terrible" post there are hundreds if not thousands of happy people with no quality issues whatsoever. But you never see them post. It gives the impression that the quality has gone down whilst it might have always been the same (if not better).
It's the same with war and peace. We live in the safest period in history but with all the news of terrorist, wars, (insert fight on youtube at walmart) it gives the impression that the world is unsafe. It's not.
To hit it home even more - when you're an exotic dancer and all you do is sleep and work at the club, you start to think all men are *******s. You don't know better but what's really happening is that you live in a bubble. The same thing is happening here.
I've got $40k of LV stuff all bought in the last 3 years and only had a quality issue with one item (a backpack that started cracking). It happens, not a big deal. Got it replaced and moved on with life
