Eh, you're wearing clothes 90% of your life...seems to me like a worthwhile area to invest in nice stuff. You can be the guy that's like "I WEAR CLOTHES SO I'M NOT NAKED ALL THE TIME" but for the rest of us we have fashion. There's a pretty massive price gap between cheap cotton and cashmere, faux leather and deer skin, sweatshop denim vs selvage denim. Labor ain't always cheap either, not everything is made in a sweatshop! And yeah Gucci, Armani, etc aren't for your average Joe, the market are the millionaires and celebrities of this world who have no reason NOT to buy the absolute best.
I don't see why there's so much hate...ANYWHERE you look there is ALWAYS going to be a highly expensive alternative to the norm. It's called luxury and it's out there, get used to it. It's like getting pissed off that Rolls Royce exists and exclaiming that all RR owners are "stupid" for buying into it.
