Sure, I get it, it’s naive and idealistic. However, as a counterpoint I have seen repeatedly that people actually go a bit nuts without interesting work or hardship. I think that’s why puzzles, video games and dramatic television shows are so popular.
The problem is that we want work that is accessible, and interesting. It should be right near the edge but firmly within our abilities to be satisfying and meaningful, and we have problems when it deviates from that significantly.
It’s possible that for wide swaths of people that edge won’t keep up with the edge of what is not automate-able, but I think a) accepting that someone people will have to be supported out of work and b) others can have their personal ability edge pushed further with vocational training is both good for those individuals and good for society.
