I would suggest to teach and emphasize the role of science and technology for our future. Social esteem for the role of the scientist and technologist is important to nurture scientific talent. Reading Paul Drucker book about how America respect for the technological man and British respect for science man explains why America took the lead in technology. For young people motivation to solve some very important problem by means of science and technology and giving them freedom, good money and respect is the right combination to make the any field advance.
