The thing is a lot of companies use Chinese manufacturers. Just about every cosmetics company, large clothing manufacturers, technology manufacturers, smaller 'British' companies. How well they do their homework and keep tabs of worker's rights and conditions is a moot point. Look at the history of ming for gemstones, yet how many wear naturally mined diamonds? What about antiques and how they were produced? There have been many scandals.
Do we check out every company, all their practices? Short of scandals coming to the public attention it can be quite difficult. So whilst I might not order huge amount from the likes of Shein and Temu I have before.
The thing is not to over consume.
