Yes democracy is helpful to prosper the people by applying their potential to grow in every field of life as compare to non democratic system wherein hard rules are applied and people fight for their rights rather to blossom.
In addition, democracy is something that you can show to people as a leader and also stuff to hide your dirty movements. In a democracy, you will be able to get things easy and make your profile nice to the people of your nation. In my country, as a citizen, I have seen my country went down because of this democracy because the leaders of the nation also had the chance and democracy to corrupt billions of billions of dollars. They have taken advantages that abide by the law and that is the true thief.
