Both Obama and Prada possess a power over society, however the source, motivation and ultimate utilization of their power is different.
Prada: Economic power. Industrial. Her power is the company “Prada”. She had to ‘capture’ the attraction of society to gain her power. She could lose her power at any time, thus she must constantly work hard and exert her power to keep it. The building is the power. Prada is moved by the building. The building must constantly ‘work’ to sustain its power.
Meeting space: Neutral. This is a shared space for two powerful individuals. It is where they will have lunch, and not do business. Thus, their ‘power’ should be neutralized to create and fair and relaxing space. Avoid egotistical symptoms: create interdependence. The two separate work spaces should collaborate to create the meeting space; so that one could not enjoy lunch without the other.
This neutralization of the client’s power could be taken further, by forcing them to arrive and leave the meeting space together.
