Why vote, as we do not really have a democracy? But if we do not we will slip back from the first step toward democracy. As it is now many (most) treat democracy like a religion or a hereditable infringement on their ability to rationality.
You are choosing a group of individuals to collect our tax dollars and to use them for our individual and collective benefit. Most extremely rich people or corporations have used us common folk to acquire their wealth. The backs of us common folk’s labour have provided their rise to power and wealth. Some of the wealthy have treated their labourers with respect and fair return for their work but many did not.
Be careful whom you vote for do your research and due diligence.
