How and why do the actions of the executive and/or judicial branches affect our life?

There are three branches of the US government. They are the executive branch, the legislative branch and the judicial branch. The legislative branch makes laws. The judicial branch headed by the Supreme court- which in turn oversees the district courts- interprets and reviews laws whilst the executive branch headed by the President signs, repeals and vetoes laws. The executive branch also commands the armed forces, directs national defense and implements foreign policy. So these branches are responsible for the laws that govern the entire operation of our society. Every aspect of life that you can think of is ultimately dictated by these branches: healthcare, operation of the civil service - police, teachers, and nurses, care of the mentally ill and the physically disabled, the prison system and prison reform. These branches thus work together to create the best possible society for all of us.
