I appreciate, @Kiman, that you have brought this point up because, like so many others, I think it is important that it be dealt with “in the market”, “in the open”, not only to discuss it now but also to keep it on record for those who may have similar doubts/concerns in the future.
In my case, I can no longer avoid seeing (and I don’t mean that I choose to see it this way; I simply can no longer see it in any other way) that the commitments and sacrifices you exemplify are part of the same evolutionarily acquired instinctive/identitary soft that generates conditions (capital accumulation, poverty, wars, environmental damage, murder, abuses, etc.) for those commitments and sacrifices to still be necessary. Once those conditions disappear, their necessity and usefulness will disappear.
Although it has always been characteristic of our species to be able to reprogram ourselves, the “AF experiment” shows that we have reached an evolutionary level in which we can reprogram ourselves to radical levels, unthinkable before. It is beginning to be evident that we can make a deliberate evolutionary leap so that that instinctive/identitary soft can disappear without anyone lacking food, shelter, housing, etc. (even without lacking goals, motivation or willpower).
I think that, like me for so long, you are troubled by questions and emotions related to what to do with the conditions already generated and that will continue to be generated, which continue to require commitments and sacrifices from some individuals to alleviate the conditions of others.
I believe that the experiential answer is provided by the history of humanity itself: there will continue to be individuals who compromise and sacrifice because of their instinctive/identitary soft, as long as the same instinctive/identitary soft that generates the aforementioned conditions continues to exist in themselves and in other individuals. But history has shown that those commitments and sacrifices will continue to be insufficient to change those conditions.
To take your example, the same instinctive/identitary soft that leads those parents to have children in the first place in unfavorable conditions and then to work their ass-off for them in order to save them socio-economically (as it happened to my parents), is the one that cannot help but strengthen in those same children (through instruction or mere example) the very instinctive/identitary soft that they already bring (oriented to fear, to attack, to compete, to accumulate, to resent, to covet, to seek to be loved, to seek to belong, etc). These children, in turn, will do the same with their own children through various commitments or sacrifices that may alleviate some of their sufferings, but which will perpetuate the causes that AF invites us to attack.
Finally, even if we take it as true that those who are actually free cannot or are not inclined to compromise and sacrifice, they are the only ones who effectively break the vicious circle. They break it by ceasing to be a link in the circle. They can also collaborate to weaken -as in this forum or personally- other links/persons that make up the human vicious circle.
If I am poor, it might be convenient, as you hypothesize, to have parents willing to compulsively work their ass-off (my parents did that; especially my mother since she was 10/11 because she was poor, father dead at 9, living in a room in a tenement with a shared bathroom; mother a seamstress, sick and finally invalid that she had to take care of; two children that until my 13 we slept in a dining room, etc.).
If I am in the middle of a revolutionary war, maybe it would be better for me to have Rambo by my side instead of Richard (for personal and family reasons, I have known directly and indirectly several of those who have participated and even died and killed in the name of “that body and every body” here, in Argentina; also the “side effects”, like my best friend being raised by her grandparents after recovering her from the kidnapping she suffered with her parents, who were then “disappeared”; or one of my friends who was born in captivity and given up for illegal adoption before her mother was tortured and killed).
However, if I want to eliminate the causes leading to need those commitments, sacrifices or revolutions to help the poor or in the name of justice, I think it is better to have next to me those who help me to stop being part of that cause.
Even if actually free people would do nothing more for others (for me, for you, for a poor child) than stop being who they were, than influence those who directly treat them (unless they isolate themselves in a cave) and than leave their testimony/responses as several have done (Richard above all, of course), I simply can no longer see any other better way than self-immolation -however slow or imperfect it may seem/be compared to other forms of diffusion/impact- to truly and causally help “that body and every body”…
