So - your theory is that a loan practice which has been illegal since the late 1960's is responsible for the current high and growing crime in Chicago? What's the mechanism for that?
Korea, Israel, Czech, Hungary, Poland, etc etc. The data strongly contradicts your implied thesis.
But you think people born in what is one of the wealthiest cities in the world shouldn't be compared to urban Indians or people (like my dad) born in a mud hut.
