It's the human nature to balance work and rewards. My problems trying to push Steem into low income communities come from:

-distrust in general( of social networks, of the income source, of the technology and of cryptocurrency)
-basically they didn't even start to contribute and they are afraid that the bubble will implode with their future worth :)
-the possibility to cash out( they WILL cash out every single penny at least for the first couple of months, I am sure of it) They don't have access to crypto markets and just want an easy way to get that money out. Trying to convince them that crypto is the future is useless since they can't buy bread with crypto and switching their communities to crypto and changing the way they all think is a not a real option.

I will seek more answers, maybe we can try and help them somehow.
