My friend, in my view the source of many problems, which are tormenting us, is our system. As a society we developed in a herd. A herd which is nothing without masters.
Man was free when he was a hunter gatherer. He was free when his tribe was small. But when he united as a society and came under the authority of state, since then he lost his independence. Authoritarian regime as well as in democratic states have maintained his slavery till now.
We developed as a society and had progressed profoundly by this union but it is also true that in that process we had to compromise our individual sovereignty.
We had an illusion for some time that we would be free and individual sovereignty would be restored once we have a chance to elect our representatives through election process, the backbone of the democratic system. But what democracy has done? It has turned into a tool which only serves the purpose of powerful. We have lost our independence because the notion of so called 'welfare nation' has deceived us because for everything we became dependent on the state. We are not free to roam wherever we want, whatever we want to do just because the boundaries of the nations and the system of the government has turned us into a tool which only servers the powerful elite.
Our over population is also the main cause of our suffering because it has increased the competition and struggle for living extensively. It has also given chances to our masters to control us. It is a very deep subject, hence, I cannot explain everything in a single comment. In one of my previous post, I had tried to discuss these issues. I will also wright on this matter in near future.
