I don't think A implied B either. B is implied through observing the behavior of simpler animals (which are easier to observe than human) and noting that it is generally self interested. Without any compelling reason to determine that man is somehow not an animal, it flows that humans also follow the same behavior.

In this case B != B prime. By that I mean that the evolutionary drive to pass on one's genes is not the same as a human's happiness.

Even natural self interest is more subtle then it would appear as there are corner cases where your genes work against you, like in many social insects.

But humans are self ware and capable of advanced tool use. I'd have to consider crack pipes a tool and smoking crack the shortest path to the greatest and most self contained happiness.

But objectivism isn't simply a repetition of natural selection, nor is it an argument for drug fueled oblivion. Franky I'm not sure what it is?

How do you define advanced? The whole 'animals' don't use tools seems to have been decimated by repeated findings over the last decade, the 'advanced' proviso is new to me.

Objectivism flows on from the idea that humans are self interested, that there is glory to be gained from achievement, that achievement is provision of something of unique value, and that money is the symbol of that unique value.

Though the language can be somewhat blunt, it's objectivism that holds dear the uniqueness you are awarded for providing in a successful startup, versus the hackneyed socialist 'money is the root of all evil' credo.
