The one thing that Saves us and Kills us

After losing World War One,the Ottoman Empire (now Turkey) beleived that the Armenians sided with Russia. And because of their utter defeat, the Turks wanted to eliminate the whole population with hopes that Armenia would never side with Russia, and never again be defeated. Solo artist, Serj Tankian, devised an amazing song that both describes our everyday problems here at home and also pulls the melodramatic veigns that keeps our hearts beating.
His song describes many things, but there is only one theme in this song. What is really Saving Us?
The music video focuses on a homeless man. You can see that he is holding a banner saying homeless. In my point of view, this banner describes this person's problem with life. the video later focuses on other people, them too holding banners with their problems written on. Nevertheless, it describes all the problems we have to face once in a while.
