This will be unpopular, but: what if an uncomfortably large part of the population just really doesn't have anything economically worthwhile to offer in the modern context? Nobody wants to say that, but if it's true, then something like a UBI or dole (even granting the author's problems with it) is all we can do short of mounting a massive Plato's Cave-like conspiracy to convince people they are doing something usefu…
Sure but that's dangerous if you skip the step of recognizing that people can have value that's not based on their ability to create capital.
We -- you, myself, anybody reading this -- aren't just "creating capital," we are fulfilling our life's ambitions. It just so happens that the free market is the best environment to explore and drive towards something better than what 90% of the other comments are complaining about (reductio ad absurdum lives of complacency.)
Creating capital isn't the end to a means, it is a means to an end.
