This Vox piece on 5 products you buy that drive human rights abuses is good enough. I talk about the shrimp industry at some length in my forthcoming capital mobility book. If you are buying frozen shrimp, just assume you are either supporting slave labor or something way too close to it. The apparel industry is of course notorious for its exploitation, as is chocolate production.
But the larger point that the author doesn’t make is that most of the products you buy engage in outright exploitation because the system of capital mobility allows corporations to exploit workers and destroy ecosystems around the globe with impunity and the outsourcing and subcontracting system further makes protects corporations from accountability. So sure, these are horrible industries but if we want to do anything about them we have to think systemically about the system of modern global capitalism that creates these horrors. And the article doesn’t really do that.
