Investments in influencing the restructuring of the education it is necessary to bear in mind that
The cost of secondary education to the student should not exceed the expected rate of return to him/her.
The enhanced earning capacity through more years in the education system has to be sufficiently attractive. For example, whether the cost of management education in the USA which is borne by the individual is worth the return on the investment, has been a matter of debate.
Education should contribute to the development of a workforce with cognitive skills. At higher levels the system should be able to produce symbolic analysts and knowledge employees for the brainpower jobs of the future.
