What are the motifs in Capitalism, the Unknown Ideal by Ayn Rand?

Capitalism vs. statism is always a recurring idea in the book. Another common element running through the book is capitalism versus statism. Capitalism, or laissez-faire economics, is a system based on freedom and individual rights. All economic entities have the right to act in their own self-interest. They are not expected to sacrifice themselves for the good of society. They make the choices most consistent with their own abilities and wants, whether they are buyers or sellers in the input or output market. As a result of functioning on the basis of competition and the self-interests of all buyers and sellers, it is a system that results in an abundance of output.
