That is all perceived reality. When one sees red, another sees pink. Which one is reality? Making sense of the world is just your brain's interpretation of the signals you receive when interacting with your environment. People have lived from points 1 to 5 and have had fairly happily lives - some amazing lives - so it's not just external situations that determine whether your life is going to be good or bad. A filthy rich man can still have depression and perceive life completely differently to someone who is financially unstable. And that example features just one external factor.
And why deny the right to be a happy slave? What's wrong with that? If they are aware of modern slavery (your points from 1 to 5), then why can't they live a happy life? Just because they are perceived as a slave, does that automatically default into you-will-have-a-long-and-depressive-life? Life is also about comparison. What you have listed is nowhere near as painful and soul-destroying as some other people's lives. I'd rather have all the problems of a conventional life than some others out there, which are truly terrifying.
In my opinion, we should be striving to open the mind and realise how strong it is. In one of Stephen Hawking's documentary he said that life has no meaning but people create meaning (the mind). Some people may have had the same crippling condition as him, or a similar one, and have lived just as long as he has, but have viewed it as an all-round miserable existence. His documentary also said: how could you even prove that a table exists without a sensory form? (Suppose it's like the saying that if a tree falls and no one's around, does it still make a sound?) Just like you can't even prove or disprove Last Thursdayism (you could've been created 5 seconds ago). Einstein is also another legend, with fascinating ideas, experiments and theories on what reality is. Broaden the mind and you won't be cocooned in just one version of reality.
Your brain rebuilds a memory from a few key features and fills in the missing details based on associations and implicit and explicit knowledge.Your brain just makes it up! A person has no way of knowing what is recalled verbatim and what is constructed.
Herein lies the superpower we all have. By purposefully effecting the variables determining your brain’s interpretation of the world around you, you can change your brain and life for the better.
The key is to become conscious of and take control of your thoughts and mind. Remember that your brain factors in subconscious beliefs and attitudes about yourself, others, and the world when assigning meaning to incoming stimuli and in this way, creates your reality.
These are the relevant words to this thread: creates your reality. Just because you view it as modern slavery that only causes depression, another will view it oppositely. Both are realities: what makes yours more real? You both may even have the same external realities but perceive them differently.
If you truly believe what you are saying, then isn't your argument with reproduction? Shouldn't you be shouting and raving about how immoral and stupid people are to bring yet another life into this world, thus perpetuating the entrapment? There will be people who will 100% agree with you, yet have or will have kids, thus making them whinging, hypocritical babies themselves.
