Workers making clothes for the retail giant Shein work unlawfully long hours and are paid poor wages, an independent research has shown. The company uses cotton from the Xinjiang region, where the Chinese government forces Uyghurs to work, including on cotton plantations. And Shein transfers inventory risks to suppliers, who subsequently dump their leftover products in low-income countries.
The problem is that it’s likely most textile/clothing producers do the same. I’ve given up trying to buy socially responsible, as it is impossible unless you are rich.
Temu, Amazon's 3rd parties, 3rd parties on Walmart, probably Walmart and Amazon too, are all getting their clothes mostly from the same places. I ordered some shirts from Walmart and then saw the same ones on Temu for half the price, so I ordered a couple of different designs from Temu, they look, feel and fit the same. All made of polyester too which is just as bad as them being made by slaves.
Sadly, the cost was the driving factor in ordering and probably is for most people on these sites.
