For everyone who's replied with "haha well no one thinks it's about boots [even though I literally quote someone who specifically cites boots], it's actually about how you spend less if you buy quality", please name the classes of items that are significant expenses where, as you get richer, you spend less by buying better items.
Multiple people I talked to found this bit — what major expense do you spend less on as you get richer? Food? No. Clothing? No. Housing? No. Medical care? No. etc.
