And you're technically right about classical Puritans. They would regard a lot of what we "do" today as BS make-work, not true work. But I think that distinction has been lost. The "work ethic" is an example of what I call a "zombie idea," an idea missing its head that continues to march on through a culture and eat peoples' brains.
This is difficult for me to understand. How can you tell the difference between resting hands (easy to defend, imo), and idle hands?
I always divide my time into two basic phases: productive and consumptive. Either you are creating something or you are consuming something. Sitting around watching TV is consuming; creating a tv show would be producing.
I think both activities are valuable and have their place. Sometimes you need to relax and enjoy a passive activity, but what makes society great is the production of new things; be they art, science, entertainment, goods..
I tend not to judge the WHAT of the creative side. It doesn't matter what you create, but the creation of new ideas and things is what makes us human.
The old-school Puritan would prefer you spend time teaching and raising children than helping an ad company sell more clicks. Or generally make a Skinner box.
Don't know much about Soviet Russia but 19-teens Russian avant-garde art was pretty boss. To say nothing of Kandinsky.
My perspective is that idle hands are actually idle: not building, not thinking, not active, not contemplative, not searching, not trying, not even resting. But idle. Un(der) used. And rather hard to defend. Consumption is easier than creation.
