You might want to Google "The paradise within the reach of all men, without labour, by powers of nature and machinery : an address to all intelligent men" ... a book from 1830 ...
The only reason for why we are still working 40 hours a week instead of 5-10 is because we are stupid ... stupid enough to listen to morons who keep talking about "growth" and "creating jobs" ... stupid enough to realize that we don't need "growth" and "jobs" but purchasing power ... and purchasing power can be generated by incrementing an integer value within a database ...
And so we watch how 3 billion #bullshitjobs are destroying us, our society, our biosphere and our climate ... they cause traffic jams, they waste like 75% of our resources, time and energy. We need to get rid of them and people who tell us that we need more pointless jobs.
For those who care ... a short list of the most obvious #bullshitjobs ... there are far more if you consider that people with irrelevant jobs lack the time and energy to aquire meaningful skills and so they will need other people with relevant jobs because they only know systemic garbage about tax-accounting or stuff like that:
Most of us are already familiar with the concept of <a href="http://strikemag.org/bullshit-jobs/" title="On the Phenomenon of Bullshit Jobs - STRIKE!">#bullshitjobs</a> - i.e. the circumstance that most of our jobs are purely systemic and that they do not benefit humanity. The most obvious examples would probably be marketing, lobbying, tax accounting, real estate brokerage, banking, working for insurances, accounting, cashiers, etc. - basically all the jobs that are a symptom of maintaining a fear, ego, competition, artificial scarcity and market based economy and the resulting value- and incentive system.
Then there are less obvious #bullshitjobs stemming from systemic redundancy. We got a thousand companies producing a thousand different mobile phones, wrenches, cars and a million other things. So each company employs its own researchers, engineers and other people doing rather meaningful things (compared to the aforementioned jobs) but their overall headcount is just ridiculously high because of said redundancy. We could probably get rid of 90% of those headcounts by "only" producing 20 to 30 different (highly customizable, individualized) high quality mobile phones, wrenches and cars in a cooperative, open-source manner without having to maintain a thousand individual R&D labs, a thousand individual marketing, legal, human resources and accounting departments and without any asymmetries in the context of R&D or knowledge and without having to care about patents or law suits.
A special breed of #bullshitjobs represent those jobs who are currently considered to be highly relevant jobs like charity, social and street workers, psychotherapists, etc. which also would become obsolete within a sane, cooperative socioeconomic environment. Well, we might still need a few psychotherapists but clearly not nearly as many as we do within our contemporary socioeconomic insanity.
