Survival in today's world demands a basic cunningness which is 'get as much as possible & give as little as possible' . If you don't exploit, you 'll get expoited............now where does the institution of marriage stand here? Wait for the times when it will be anhilited & we will have factory made progeny. And this is no unrealistic imagination. It's inevitable future of our species.

And, human beings are not social animals. They form societies to ensure their security & well being. If there is an alternative available to ensure lifelong supply of their basic need such as food, sex, shelter & of curse a painless death; nobody needs any society.
