How exactly are you forcing these workers to produce your product? Are they willingly passing on other, better opportunities to work in the factories that supply you? No doubt by our standards what they earn is pitifully small and the amount of work that they have to do would be refused by most in our society. This however is a sign of the vast difference in wealth and development between the country of production and the country of consumption. Without this differential we wouldn't buy anything from them and they wouldn't even have that meagre income potential.
You may define this as exploitation, but it can be the primary source of development capital in less developed countries. Slowly but surely this influx of foreign money DOES have a broad general influence in improving the state of the economy in those countries. When I was young Japan, Taiwan and South Korea were the low-cost labour pools to produce our disposable items. Now look at them compared to their neighbours. China was later, but even now as the standard of living there (very slowly) begins to increase there we are looking at alternative, lower-cost producers (Vietnam, Indonesia, etc). However, now they have much better opportunities to fulfill their own (increasing) domestic demand with the tools, skills and capital that came to them through the earlier "exploitive" trade.
