Look after the interest of ordinary people

I watched an interview with a US Senator on television.

He argued the case for a change in some tax code, so that "the tax can be applied fairly to all". He said that it is his duty to reflect the wishes of his constitutents in the legislation that is being passed in Congress.

In the globalised economy, it is important that there should be voices to look after the interest of the ordinary people. The US system of democracy appears to handle this matter quite well. The issues that affect the ordinary people are brought up and aired in the Congress.
