As I said earlier I believe that Samuel Beckett wrote this play as a complainment to the society. I believe that it is about the cowardness and "zombines" of most of people. All through out Beckett´s "Waiting for Godot", they, Estragon and Vladimir, end up never doing anything and always deciding to wait for Godot to decide for them. This shows that people are not able to decide for themselves and just like sheep need to be told what to do and be guided through out everything.
They are also waiting. Everyone is waiting. Everyday. Waiting for something. Something to start, happen, end, etc. Thus I think that Samuel Beckett´s "Waiting for Godot" is about society and philosophical society questions. Throughout this play he is trying to point out these problems and in a way tell the people (society) that they play a similar role to Estragon and Vladimir.
