Why do we need to work?

I often ask myself this question, "Why do we need to work?". And I had a myriad of answers to that question, as follows;

1)To kill time

2)To do something useful with our lives

3)To give ourselves a sense of empowerment that we are independent and not dependent for anything

4) To earn money

5) To earn money

6) Money

7) Money

8) Money

9) $$$$$$$

Yup. Why do we work? For money!!. That's all. There is no other reason why we work. If you say u work because you enjoy the challenge it gives you. You might say that for a while, but over the long haul, it's strictly for the money!! We force ourselves to wake up early in the morning, force ourselves out of bed, put on some nice decent clothes and head to work and mingle with the colleagues and complain about a whole myriad of issues from the the jams on the public transport, to the bosses and other colleagues, etc and then head back home and continue what we were doing.

It makes you think. Why are you doing this exactly. To survive in this world, we need money to pay for our bills, food and so on. And this goes on till our last breath. One life is over. So with this approach, is life worth living? Maybe? No?
