The pro's and con's of cheap labour on third world countries

Order Description explain the impacts that third world countries have to face because of cheap labour. What they have to go through on a daily basis to make ends meet just so big fashion industries get cheap labour. They dont care about the impacts or what work environment the workers are in aslong as it dont cost them a forturne, whether or not lives are ended. Theres reports on many fires in bangladesh in clothes factorys and people lives ended yet the fashion industry did nothing to help them. Apart from the negative side i want to look at the positive side aswell. How it helps the economy and so forth.
