Does egoism suffer from "one thought too many"?

A rational-ego means that importance is placed on the hierarchy of values. A rational-egoist would courteously save a drowning child provided that there was no sacrifice involved for either party. Defining sacrifice as the rational-egoist does not put themselves in harm's way either by lack of knowledge of swimming or some other danger that might cause the victim more harm by interfering. A rational concern for self does not imply trampling or being destructive on others to gain what a person wants instead it means pursuing your rational self-interest goals first and if along the way consensually trade with others whom help you achieve. A rational-egoist understands that long range thinking and productive achievement is important to his or her survival. Being destructive to others is what malevolent, incompetent non-productive parasitic evil men or women do. They steal a living rather than earn.
