Heller thinks that the concept of mainstream vs underground because they rely on each other.  The mainstream takes from the underground, and transforms it into something acceptable to the public, whether it’s a product packaging or hobbies, the underground joins the mainstream in order to use the resources it provides and change it from the inside out  or uses satire to make fun of the mainstream.  Stefan Sameister fits in between mainstream and underground, but leaning slightly to the underground.  Sagmeister works are daring and can be controversial at times, not what the mainstream would take a chance on, the main stream wouldn’t risk profit and reputation, but Sagameister would likely take the risk.  Tibor Kalman works and philosophy has  influenced Stefan Sagmeister works, from execution to  the provocative designs.  While Kalman focuses more on social and environmental issues, Sagmeister focuses on broader things and emotional impact of their work that are considered taboo in society.  Stefan Sagmeister work would influence future designers to be more daring with their work and take more risk in order to innovate and think about their social responsibility.
