Why is everyone so defensive? The author never says we'd be better off living in the pre-industrial era. It just points out one of the many lies we've been pushed on by the modern propaganda. This kind of emotional reaction shows a level of insecurity that usually only comes out when we are attacked on something personal we feel fragile about. I don't understand how a discussion about the merits of capitalism can trigger the same response in people. You don't react like this when you're confident and certain that you're doing the right thing. The point of the discussion isn't if we should go back to the pre-industrial era. The trillion dollar question is sadly left unanswered and, worst of all, undebated: If productivity has constantly risen since the first industrial revolution, why do we have less free time than ever? Where have most of the productivity gains gone? Before I get answers about how we have less housework to do in our free time today, for most people working full time that is simply untrue. You commute ~1 hour daily, work 8 hours, when you get back home you've got to buy groceries, shower, cook, wash your dishes, etc. There's barely 1/2 hours of leisure left, and we usually feel too tired already by that time.
