I think more people do but it’s genuinely quite hard to know. If you walk into a shopping centre, you need to buy some pants. There are 8 stores that sell pants, in each store there’s some price range from low to high with some overlap, maybe the range for the cost is 5 dollars to 300 across the whole shopping center.
Which pants were made by slaves? There’s no label, the 300 dollar pants are still mass produced cotton and polyester crap probably made from cotton picked by literal child slaves. How do you decide? Ever company puts up signs about responsibility and ethical supply chains but there’s no enforcement so it means nothing.
There are some specialty sellers online but they’re often extremely expensive and not widely available. Is that the real cost? are they honest? Buying the 5 dollar pants is probably terrible, are the 50 dollar pants 5 dollar pants with a 1000% mark up? If so you’re even worse for buying those :/
