Andf thsi seems like an appropriate time to introduce Dr. Fred Herzberg (Sgt, US Army, Retired) who is famous for his theories on motivation e.g., it's not always about the money...
http://en.wikipedia.org/wiki/Frederick_Herzberg
Frederick Irving Herzberg (1923 - 2000) was a noted psychologist who became one of the most influential names in business management. He is most famous for introducing job enrichment and the Motivator-Hygiene theory. His 1968 publication "One More Time, How Do You Motivate Employees?" had sold 1.2 million reprints by 1987 and was the most requested article from the Harvard Business Review[1]. Herzberg attended City College of New York, but left part way through his studies to enlist in the army. As a patrol sergeant, he was a firsthand witness of the Dachau concentration camp. He believed that this experience, as well as the talks he had with other Germans living in the area was what triggered his interest in motivation. Herzberg graduated from City College in 1946 and moved to the University of Pittsburgh to undertake post-graduate studies in science and public health. He earned his PhD in psychology with a dissertation entitled "Prognostic variables for electroshock therapy". He started his research on the workplace while teaching as a professor of psychology at Case Western Reserve University in Cleveland and later moved to the University of Utah where he held the position of professor of management in the college of business.[2]

Many people argue nevertheless that money is a primary motivator.
For most people money is not a motivator - despite what they might think and say.
For all people there are bigger more sustaining motivators than money.
Surveys and research studies repeatedly show that other factors motivate more than money. Examples appear in the newspapers and in other information resources every week.For instance, a survey by Development Dimensions International published in the UK Times newspaper in 2004 interviewed 1,000 staff from companies employing more than 500 workers, and found many to be bored, lacking commitment and looking for a new job. Pay actually came fifth in the reasons people gave for leaving their jobs.
The main reasons were lack of stimulus jobs and no opportunity for advancement - classic Herzberg motivators - 43% left for better promotion chances, 28% for more challenging work; 23% for a more exciting place to work; and 21% and more varied work.
