Sorry if this might come as rude or elitist - not my intention as I've been there, but I'd really recommend reading some theory if you're interested in this kind of stuff. Even some shorter works of Marx & Engels will dispel A LOT of misconceptions a leftist might have about socialism/communism/what's actually the problem/etc that one might get just via osmosis of the popular discourse.
Now to respond to some of the points (though not all, too tired right now):
My point about workers not getting full value from their labor mostly targets the wording in the meme, it's pedantry. Whether you think it's fair to count taxes or not isn't really relevant, but the fact that you have a system where whether you like it or not the state will take away some of your earnings from your labor means that you cannot really receive the full value of your labor, something always will get deducted. Though there was a better example of this I should have used, directly related to labor that you end up making:
Agreeing with your fellow workers to take home less pay to keep the factory viable is not exploitation.
Taking less pay in order to compete in the market economy is literally what capitalists do on behalf of workers - take their surplus value to expand production and remain competitive (and ofc live off of this surplus value themselves individually). In a coop, this would also happen under a market economy as you yourself say, and this money will come from the value of the commodities they produce as in the fruits of their labor they're supposed to be getting "full value" of. See how it doesn't make sense?
Also, I admit I should have asked this previously, but what exactly is socialism defined by for you? Based on your comment, I gather that few things exist in this socialism, and those are:
- Commodity production and markets remains in place
- Surplus value is still being appropriated, but democratically
- Getting taxed by the state to help the community via public services
- Money remains in place as value form, meaning capital accumulation is still possible
- Something that can be achieved through reforms if enough people believe in it? (idk about this one but that's what i'm inferring)
Now I might be wrong about these and maybe you have a different definition in mind, but this is pretty much identical to a social democracy which is still fully capitalist. Coops exist within capitalism right this moment in some countries - individual companies where workers collectively own the means of production, but they still have to play within the rules of capitalist mode of production.
Sure, it might be better but socialist/communist goal isn't to make things better, but to change the current state of things entirely. This is why actual socialism, which is defined by figures like Lenin, Marx and other non-falsifier communist theorists has markets and commodity production already abolished. Before socialism after workers take power, there is a period of transition where commodity production at least partially remains in place as a way to distribute goods while productive forces (like factories and infrastructure) are still being developed so everyone's needs can actually be met during socialist stage.
Money gets abolished in favor of labor vouchers that get discarded after being used up (so there's no more accumulation of capital), things start being produced for use - there's still a long way to go towards communism at this stage, but this is how you actually stop being capitalist and create a separate mode of production instead of just making things a bit better but still fundamentally capitalist.
Anyway yap yap nobody reads this as seen from the amount of upvotes, still had to leave one as it would have felt rude if I didn't and just left you hanging there
