Earlier quoted context omitted.
Even without capitalism, you have a duty to create value for the people around you, and you might expect the same of them. There are exceptions for the young, old, and infirm.
In no world where there is a "duty" to provide value am I going to be found happily providing value. In this world, in my experience, your statement is simply false. If I happen to provide some form of value it is from my choosing to, not to satisfy the demands of some formless "duty".
Who is going to create all the value consumed by rent seekers, financial engineers, thieves, scammers, corrupt or bloated government? People who create and provide more value than they consume.
