The contract was never written down, though. And it could never be written as the rules are in constant change. Even the contract itself is just an assumption when at some point in your life you look at how people live, how they have been living in a relatively short period before now, and based on that you assume the existence of a "contract". Apart from your assumptions, nothing exists, we just hope things work according to our expectations and make decisions in our lives based on that.
