It is merely a theory that explains how free enterprise works. Banks for example, a very important part of the economy, are left out. Some socities do not accept the circular flow model theory.

The United States Constitution states that the Vice President of the United States is the President of the Senate, despite not being a senator, and that the Senate must choose a president pro tempore.
The President pro tempore (/ËproÊ ËtÉmpÉriË/ or /ËproÊ ËtÉmpÉreÉª/), or president pro tem, of the United States Senate is the longest serving Senator from a major political party in the United States Senate. According to the Constitution, this is the fourth highest office in the United States.
