I just finished Slow Productivity and once again I've been left wondering, who are productivity books written for? On one hand Newport does his best job to date addressing workers that don't have full autonomy over their working environment and tasks, and on the other hand his best to date barely addresses the subject at all.

I suppose that any book is written for someone that has the extra time to sit down and read without the need for income. That mostly eliminates those that work many jobs to make ends meet. Thus the market for productivity books by necessity must be an affluent market. If that's the case, can I really fault the author for not addressing how someone in poverty would take steps towards being "productive"?
