In reply to Ennerdaleblonde:
It will depend a bit on what brand you're looking at. Brands are not charity organisations, they have to operate at a profit (at least in our current economic model).
If you're looking at fast fashion, then yes, margins at the brand level are ridiculous. It's not unheard of that something that will retail for 25-50 (the cost of a T-shirt nowadays, even with fashion brands) to be produced for almost literally peanuts.
The brands we're looking at (whether that's Arc'teryx, Rab, Fjällräven, Mountain Equipment, you name it) are to some degree or another, selling their stuff to a more limited user base, which means lower order numbers, which means higher costs per piece. Also, these brands, by and large, are at least paying some attention to CSR. Still, they have to operate at a profit.
