Social responsibility and basic needs
As social creatures, our responsibility and our needs don't just stop at taking care of ourselves. Being nice integral to our growth and the well-being of our society. So to say that humans need only leisure and the ability to engage in creative pursuits to sustain themselves is only partly true.
We need opportunities and the privilege to exercise compassion. Those of us that are fortunate enough to have enough capital to become self-reliant must also aim to be a little more than self-sustaining. So that we can help those in need. It doesn't have to be a lot, but creating a positive, strong, meaningful impact in someone's life is critical to reconnect with our humanity and truly realise what it is like to be human.
