Do laws even matter today?

I agree with Jonathan Turley, a Public Law Professor at George Washington University, that double-standards and arbitrarily legal practices are relevantly related to both Law and Politics. Politicians write laws, and laws are practiced by politicians.

Since Democracy is run by Representative System, the people, who actually have the right to direct the country, tend to practically have less power. While those people who hold governing power tend to arrogantly adore their power and forget about who, in fact, giving the power to them, and in order them to achive what. If these people, the politicians, could recall the intuitive intentions of what democracy is and why a society needs laws, all the controversial problems would not even have been mentioned.
