Both you and @Outtatime@sh.itjust.works have a point, and miss it by a bit. It's not the point that a job that could be done by a robot is automatically useless, or that working in a trade is damaging.

• Not the type of work does the damage, but the daily hours you do. Whoever said that every job must be done 8 or more hours a day? Can we call it a day at 12:30 if the work is heavy or damaging or monotonous? If I type 8 hours i suffer as much damage as a trade person working 8 hours, just in different parts of my body. Same for people who drive 8 hours or paint 8 hours every day.

• If we got out of the mindset that a real job is something we have do at least 8 hours every day, we could do illustration, raising bonsai, writing novels in our free time. Without the pressure of survival in our necks. But we hand over most of our productivity to whoever owns 'our' corporations these days. There's no need to do this anymore, we can get together and stop this.
