Maybe you just see capitalism for what it is [1]. If so, this might be the wrong forum for you to be asking that question on. On the other hand, not every job is unproductive busywork (despite being for profit), so maybe you're just not feeling well or you've had exceptionally bad luck?
As someone who lived through communism - this kind of phrasing is really dangerous. What people complain about on /r/antiwork is problems that people from my country would kill to have.
Capitalism has it's faults, but just complaining, without a constructive alternative can lead to way worse outcomes.
Worker ownership of the means of production (i.e. democracy at work) is an alternative and that's most certainly not what you lived through, nor did you live through a stateless, classless and moneyless society. What you lived through was fascism with red flags.
If you check the sidebar of that subreddit you'll find anarchism and mutualism as the solutions to the problems it identifies.
> What you lived through was fascism with red flags.
What makes people believe that further attempts at implementing this utopia will not just end as another cases of fascism with red flags? Certainly so far all previous attempts ended up this way, and there was a good amount of them so the sample size is not small.
Prefigurative politics. Your groups to change the world operate in the same way that you want to see the world be in the future, not in ends-justify-the-means vangaurdism. If you intend to implement democracy, you operate as a political group democratically, etc.
It's almost as if there's a class of people who own most of the world's resources and entire heavily armed states who have an interest in ensuring that failure at all costs, you might say.
Then again, it's been tried plenty of times. That's what cooperatives are, family farms are, what you owning your laptop as a programmer are. We just cut down on the coup d'etats and union busting and expand that kind of democratization of the work week to everyone.
It's also a silly argument considering you could have said the same before agriculture and before capitalism succeeded.
All of human history was workers controlling the means of their production until about 10,000 years ago, when class society was introduced in parts of the world, with one class who worked, and an idle class that did not, expropriating surplus labor time from those who worked.
Unexplained labor still exists deep in the Amazon and elsewhere, but mining companies finding new traces of valuable minerals are extinguishing the last of the old free way.
This shouldn't be a hard question for you to answer for yourself. What do software companies produce? Software. What's used to produce that software? That's your means of productions: IP, desks, chairs, laptops, routers, development software, etc.
Everything on this list but IP is entirely inconsequential. The primary means of production are the workers' brains, which they already own. This shows how the XIX century Marxist thinking is completely outdated in XXI century.
> Capitalism has it's faults, but just complaining, without a constructive alternative
Classic "mudding the waters" line, it could be written by a plugin these days. The fact that you don't agree with the alternatives doesn't mean they aren't out there and people "just complain".
