Eastern Germany, which was meant as model propaganda state to show the west that socialism works and everyone is happy under socialism also had the directive that there is to be zero unemployment in the entire country. Seriously. As everyone knows who knows only a bit about the complexities of the economy of a bigger group of people, (like a country) effectively this is impossible. Mostly it was solved by shoving ten people into a job that could be done by one person, which lead to such interesting situations where workers would sit around in factories that would produce nothing (as supply with resources was unreliable in quite a few industries) and would spend their time at work drinking with buddies and building very elaborate recreational facilities. I'm not even exaggerating. If you have ever seen one of the episodes of MASH where the doctors were bored out of their minds because there were no wounded, it was kinda like that.
It also was impossible to get fired from a job pretty much, which led to such situations as that you could go to restaurants to eat and find the whole staff chatting and hanging out with each other and ignoring the customers, if you complained, you simply wouldn't get any food until you left, as opposed to just waiting for an hour for it. These experiences also all disregard the intense thought policing, non-existing privacy and other human rights violations that happened. Everyone who had two braincells to rub together hated living in that country.
We already have a problem with employment as new jobs aren't created at the rate they would be needed to to even keep up with population growth and the "computer revolution" and the non-preceded automation is destroying jobs without replacing them with better ones in sufficient numbers (which is very unlike every other technological revolution we had) either we curb population growth a lot (which might not even be sufficient and which is a problem with current systems) or just get used to the thought that there will be people that'll never work. The current approach is to undercut the machines by making human labor so cheap that automation is expensive in comparison, but even this will not work forever (see: even McDonalds automating some staff away) and as you can imagine, it does not exactly lead to high quality of life.
People also underestimate the domino effect technological progress can have. Take automated cars: Imagine cars that drive a lot safer than humans do. A lot less accidents happening, fewer people die. A good thing, isn't it? The obvious is that it puts taxi drivers out of a job, the less obvious is that it also endagers seemingly unrelated industries that depend on the accidents happening, for example the insurance industry. Ever thought about what self-driving cars will have an effect on insurance companies and the livelihoods of people that work there? Most people never did.
A well written, very accessible book on this topic is "Rise of the Robots: Technology and the Threat of a Jobless Future" - I have to warn it makes for some uncomfortable reading though.
On the topic at hand, it might be me becoming an old softie but I can kinda understand when some young people that sort of slip through the nets (which seems to get easier each year) and don't find a nice, livable job end up as outliers disillusioned with the whole system. Throwing the baby out with the bathwater is certainly not the solution and people are being idiots about it, but I can understand the sheer frustration of some. As older fart in my country where the middle-class had it very good I can remember a time where family fathers could buy houses and support a wife and two kids with a job that basically amounted to do customer support via the phone for bus and train tickets. The job might not have been exactly super-fulfilling and purposeful but it enabled those people to have a place in society and be proud for what they did. Can you imagine that now?
