Put another way, I'll worry about a million people not "adding value" when there ceases to exist individuals who have captured enough wealth to support a million people. The latter is the real problem.
I have no such thing. I am debt free and live the way I want. I live alone. I have no children or spouse to support. I owe nothing to anybody. I don't owe anyone an explanation. Maybe the opposing views come from people who believe they do, but in no way is it universal.
Your point from the perspective of wealth inequality is more elegant. In my case I am wealthy enough to support roughly one person: me.
If I want or need more resources, I have levers I can pull to obtain them. But don't tell me I have a "duty" to add value to the economy.
I won't name names, but I do know people who have simply not filed nor paid taxes in a decade. They even got stimulus checks.
