"People aren’t deliberate enough about choosing what to work on."
Hold up. What is this based on? Is it based on a feeling of the author's inflated sense of worth compared to others? Or is this really some objective and measurable metric?
Is it possible the author doesn't actually know or has taken the effort to deliberate on this statement themselves? Playing devil's advocate with your own ideas is probably the greatest service you can do for yourself but it seems that's not practised here. I can come up with many examples of how people ARE very deliberate in what they work on. Like you said, raising a family, enjoying time outside of work, just straight up trying to survive. These all seem pretty deliberate.
