Nike workers pay issues

Today in class we watched a video on nike and the difference in how much they pay some workers. The guy in the video went and worked in the spot of people who make $1.25 a day. Working all day then getting paid so little made him not be able to eat a lot or do anything he usually does on a daily bases. The fact he lost 25 pounds in a month because of how little he ate because he had little money amazes me. They even stated that tiger woods made enough to by him a house in a second but why are some people working harder then tiger woods but are barley surviving. There should be a change to it because soon it'll be happening with other companies too! As much as that makes me not like Nike I will still wear it because its everywhere and they're working so hard to make it we should at least put it to use!
