Do you believe in Ayn Rand’s philosophy on the ethics of altruism?  If each capable individual does their best to be their best by looking out for their own interest then they would fulfill their societal duty to be a productive member of society.  This does not mean that you cannot or should not help others. 

Looking out for your own interest and being selfish in that way does not preclude you from being generous or thoughtful.  It is each one’s responsibility to achieve all that you can. Rand believed that capitalism is the morally superior economic system and that morality demands respecting the individual rights of all.  Capitalism drives an economy for all to grow, socialism drives an economy for government and restrictions of freedom to grow.
