1. "I don't consider actively exploiting the poor as "not improving their lives enough"." and "Neither do I consider marginal benefit a positive if it comes at the cost of exploitation."
You've framed the debate as "exploiting the poor" and "exploitation" yet do not give any reason for this other than an implicit claim that sub-minimum wage is exploitation. Let's say the minimum wage is $X/hr and this project allows these people to earn $(X - 0.01)/hr. Is that still exploitation? Why do you assume just because something MIGHT not be minimum wage that it's exploitation? Minimum wage and exploitation are only slightly correlated subjects.
All the original author is suggesting is to OFFER people jobs at a rate that the economy identifies as a sustainable employment opportunity. Kids selling gum at school might earn below minimum wage but it's their choice and their life to do. Nobody is FORCING anybody to take those jobs, therefore this is not exploitation and your dramatic and emotionally overloaded choice of words really does not help you make your point. You need to take a moment to define exploitation and I think in doing so you will see your argument is flawed.
2. "I don't see anyone moving from selling drugs to doing menial mechanical turk work" OK but that's your opinion and minimum wage laws block verifying what the reality of the situation is.
3. "By all means - go and try to turn America's poor into Silicon Valley's drones rather than invest in their future"
Why do you constantly resort to such emotive, overloaded language? There's no conspiracy here; nobody is trying to "turn" anybody into anything. What people ARE saying is "Hey here's a way some people can make some money, maybe some will find it acceptable" and people like you are saying "No I refuse to let anybody explore this possibility because I'm uncomfortable with a society where people are earning less than I think they should because of my beliefs about what people should earn, and I believe that my beliefs override freewill".
Notice that your argument, as far as I can tell after filtering out the emotion, is pretty much all about your beliefs about work and society, and has nothing to do with (a) the actual state of the economy at a given point in time or (b) the actual people out there who might benefit from the proposed arrangement.
