Nope that's not the argument I was presenting. My point is not that automation causes mass unemployment, rather it pushes people into ever more pointless and unrewarding forms of employment. Rather than freeing people up to do 'better' jobs and have more leisure time, it makes people scrabble around just finding stupid pointless things to do and actually work longer hours because of unstable, insecure, low paid jobs. Is it any wonder that at the heart of the Trump and Brexit movements are low skilled workers wondering what on earth it is they are supposed to be doing with their lives, struggling to make ends meet, worrying about losing out to immigrants and wanting the return of old roles such as manufacturing, agriculture, mining and so on? But this can't return and yet there is very little retraining into 'value added' roles and not everyone is suited to them anyway. We're now a service economy, not a manufacturing economy, but once service starts to get increasingly automated, what next? No it won't be mass unemployment, but we'll have to find new ways to get our noses to the grindstone. Perhaps we'll all become creatives and flood the world with endless self published novels and mindless narcissistic You Tube content (already happening of course)? Even with all this automation, people STILL cannot cope with the concept of ordinary people not having regular jobs or being productive. Which is why we have such hysteria about benefits scroungers and people are working longer hours than ever before. There's now talk about how 'wonderful' it'll be after Brexit when we can get rid of the Working Time Directive and people will be able to work longer hours, do more overtime, have less days off, less paid holiday and sick pay and in ever more pointless jobs. This is progress? So no, automation doesn't necessarily cause mass unemployment because people always find 'something' to do, because that's how society operates, making sure people are doing 'something' even if it's essentially pointless, unrewarding or irrelevant. Those in control just need to make sure to keep most peoples work-life balance suitably messed up and pressurised that they don't get ideas above their 'station' and get too jealous of the ever rising inequality around them. Same old.
