"All in all, I think it is a mistake to defend people's rights with one hand tied behind our backs, using nothing except the individual option to say no to a deal. We should use democracy to organize and together impose limits on what the rich can do to the rest of us. That's what democracy was invented for!"
I found Roger Martin's book "Fixing the Game" to descibe interesting case studies and proposals on how to fix the short-term greed problem. Perhaps Instagram's board should read it?
For such simple services, reputation is all there is. Building next photo sharing service is easy (perhaps already free on github?) and competitors are waiting for Instagram's slippage.
The impulsivity caused by dopamine deficiency also causes more unwanted pregnancies - another risk factor for criminality.
Poor people are also more likely to be religious - http://www.gallup.com/poll/116449/religion-provides-emotiona... and being religious is correlated with criminality.
So there is clearly a strong correlation between the effects of being poor or in poverty and criminality. Since the law is specifically designed to 'deal' with criminality, it is a mechanism which is quite biased against the poor. Hence, the law is there to protect the rich from the poor.
