The similarities between the symbolic interationist theory and The conflict theory?

Social trafficking theory is that social systems are essential divided into two sectors or social groups, a ruling class and the working class, and are selected in two groups in which they are classified as "their inherent natures." The theory of symbolic interactionism is a sociological approach to human relations that considers as very important the influence, in social interaction, of the very particular meanings brought by the individual to the interaction, as well as the very particular meanings that he obtains from this interaction under his own personal interpretation.

That is, the similarity between these two theories is in the formation of social groups and how the behaviors and interactions between these groups shape the human being.
