Weird comment. I don't understand why the price you pay makes a difference. Someone could be exploited even if the price was $100. Location doesn't matter either, people are exploited all over the world.
You don't understand why the price you pay makes a difference in whether someone is exploited or not? Do you think a shirt could be profitably sold for $1, and have everyone along the supply chain be paid a fair wage?
Also it's true, people are exploited for more expensive things all the time. But my point was about cheap stuff.
Sorry, but the final price of an item cannot be used to determine whether someone along the chain was exploited.
I was in the t-shirt industry for a number of years. Sold millions of them. The base price of a raw blank t-shirt at scale is around $1-4, so there isn't much room to go lower there. In essence, from your definition, ALL t-shirts are exploitation of some form or another.
