Just because something is expensive doesn’t always mean that the standard of living of those making the product is any better. Nike sweat shops for example.
Consumers dont have a lot of transparent choices here. Governments have roles in regulating and making the true cost of products more transparent. I’d say businesses have that responsibility, but clearly that doesn’t work, otherwise we wouldn’t be here etc. Businesses dont want people feeling guilty when they buy their product, so why would they tell people.
For a business to be competitive in a harm free supply chain, then the playing field needs to be levelled. Transparent supply chains everywhere, make everyone feel guilty all the time, maybe something would change.
