Selfishness is good! Principles of healthy selfishness

Is this position correct? The answer to this question was tried to formulate in his new book Peter Schwartz, a famous American scientist who held a high post at the Institute of Ain Rand. He managed to debunk a number of myths concerning manifestations of selfishness and to establish that any of us has the right to take care of our own interests and use the resources obtained for our own needs.
