When I buy a garment, what portion of the cost goes to workers? Are 'clean clothes' more expensive than the alternative?
Suppose a pair of trousers costs €100. Garment workers as a collective receive 0.5% of the price you will pay in the shop. In this case the amount is €0.50. In contrast, the brand profits 13% of the price you will pay in the shop. In this case the amount is €13.
Now suppose the manufacturer prices the trousers at €105 with the sole aim to pay a higher wage to workers. The consumer pays 5% more, but workers earn double. (Alternatively, the manufacturer could absorb the negligible increase and maintain a price of €100 for the consumer.)
Paying higher wages therefore does not have to influence the price you pay as a customer.
