What is that “the full value” that worker should get? If for example I have worked my ass, building five garages, and now i rent four of them for someone doing busines in there with their own hammer and my multitool – what is the full value that the renter/worker should get? What is the full value if someone who rents my garage, bought his own tools, created workplace, found someone happy to make stools whole day for him and now only sells them? What is the full value if someone (garage owner, or renter with busines) decided, that 10 years of working (their ass) hard is enought and now they will live a bit slower, maybe even employing profesional manager to do their job. Where is the line?

Where the line is is debated among socialist all the time, and where you fall on that partially determines the type of socialist you are. Please read theory before assuming you have this incredible gotcha that nobody ever thought of.

The answer is quite simple, the full value is determined by the amount of profit they generate through their labor.

I understand giving everybody as much equal oportunities as possible, enabling everybody equaly as much as possible – but that does not magicaly make them all work equaly hard, equaly skilled, equaly balance their work/life/family/free time, does not magicaly eaqualy balance them all taking same risks, responsibilities.

Who cares? They're getting the full value of their labor, even if that full value is less, i think you imagine socialists believe in absolute equality for some insane reason, this is why i'm saying you haven't read the material.

What’s fair to take, to share with less efective (or happy) ones – that is the question? Should we make it harder for the faster ones, working harder ones, healthier ones?

This question doesn't make sense when you factor in the things I just said, so, i'm just going to ignore it.

How the fck not alowing to gain from someones earned capital or someones labour (by delegation of some tasks) will create equal oportunities? Whats wrong in and with curent democratic/capitalistic (semi social share and care policies having) system of western countries? System curently alowing workers to own shares and voting with their hands (as coowners) in business or voting by their feet and going to other busineses to work and own them (or building them themselves). Go and do?

Nothing is wrong with some of those parts of it, in fact, socialists aren't exactly anti-capitalist, they just recognize it's a temporary thing. The problem with people who generate money from capital is that they don't work, they make money from their money, and a class of people who simply makes money from their money are leeches on society, an unnecessary middleman between the people who actually do work, and the money they produce.

Furthermore, if you're wondering why people would still have opportunities, the answer is that a union of workers can still form a business, this not only actually dramatically reduces risk, but also is much more doable when people actually get paid the full value of their labor rather than a tiny percentage.

Please read some theory before you try online gotchas, or at least ask questions instead of being a butthole and assuming you know better. You're not using facts and logic to argue with me, you're using ignorance and guessing about what we believe.

You're kinda arguing with somebody who has actually bothered to read the material we're talking about, and assuming you can outwit it without even reading it, and it's a little like telling a quantum physicist they're wrong because quantum physics doesn't make any sense, it's painful to read. This is a set of philosophies with hundreds of years of history, they've thought of all the things you've said many times.

The man who bakes a loaf of bread in order to buy a slice is not truly free.

To understand this, read about the labour theory of value.
