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. These socities, therefore, choose another economic system other than capitalism. Socialists and communists see the role of the government in a different light than capitalists do.
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 is elected by the Senate and is customarily the longest serving senator in the majority party.Originally, the president pro tempore was appointed on â¦ an intermittent basis when the vice president was not present to preside over the Senate. president pro tempore is the leader of the Senate when the  Vice-President is not there. (pro tempore is Latin phrase which  means for the time being.) Unlike the VP, he â¦ can also vote to  create a tie, since he is a Senator. The position is elected by the  Senators.
