Big Business usually keeps many goods cheap for us in the western world by screwing over counties in the third world and/or cutting corners thus hurting peoples health and/or trashing the environment. Big Business also often decides to make goods expensive even though they are usually still doing more of the same. When Nike trainers and Gucci woolen hand bags are priced at $100 nothing tangible is affecting the price only shallowness and greed.
Sometimes, when their public image is suffering too greatly and shares drop as a result, conductors of big business need to do, or pretend to do, things that can be considered ethical to boost their image. On occasion the law can also make them do this, however crack teams of lawyers and hefty bribes handed to politicians, judges and bigwigs in the media usually prevent this, it can be said big business practically owns the areas these dudes work in.
Big business can lead to great advances being released that revolutionize our lives but it can also suppress such great advances if no profits can be made from them.

Santa: They probably invented these advanced phones donkeys ago. But to maximize profits, they have to release them in increments, wasting resources and other peoples money.
