Oh yes, but Fitzgerald certainly didn't come across as a fan of the 1920s from the way he wrote the novel and certainly portrayed it as being a hollow and relatively superficial decade. It was a good book, but I'm just not a fan.
As for Godot, I think there's a fair bit you can read into it when you think about other absurdist literature such as things by Kafka and Camus (granted I had a little grounding in it). I don't think it's something that is supposed to make sense by convention. It's supposed to take people out of their comfort zone of understanding why and how things happen in order to really make them consider their lives and take a step back from reality in order to do so. A lot of people seem to think that 'Godot' is in fact God, but as Beckett said "if by Godot I had meant God I would have said God."
