Democracy thrives on the participation of each and every one of us. It's not true that your own voice does nothing. It only does nothing if you limit yourself to making a cross every 4 years and supposedly handing over the responsibility for everything that goes wrong.
There are many people who see that the political and economic system restricts or even partially prevents democratic processes. But if you want to make a difference, you have to start moving yourself. What better way to meet like-minded people, get to know each other and achieve something together.
So keep your eyes open for appointments for demonstrations that are formed for people and against exploitation and corruption.
