The reason dept store clothes and the like is cheaper is because they use overseas labor that they can exploit and underpay. If you don’t want to own a sweatshop, and I’m assuming you don’t because most people don’t want to be monsters, you’ll have to charge extra because capitalism is structured so that ethical labor is punished and discouraged.

building on the last point, capitalist hegemony works to misdirect our attention to the price of goods rather than the price of labour. it’s not that most things are too expensive, but that we are paid too little. and that’s why capitalists will destroy the planet shipping strawberries or shirts across the planet to save on the cost of labour.
