Here in Buenos Aires we have a lot of entrenched poverty too, in slums that are often only tens of meters from rich areas.  What I wonder most about is: what is the relationship between the poverty and the prosperity?  Are the people in the &quot;labour camp&quot; able to go out and shop for meat, fruits, and barber services?  Can they go get another job?  Or are they in some kind of debt bondage?  Have they been forced out of their homes by the electronics industries, or are they sending money to their parents and grandparents back in the village?  Are the street food vendors and desperate taxi drivers better off than they were before the electronics industry came along, or are they finding themselves unable to pay the escalating bribes and taxes, forced off the land their families farmed, and occasionally beat up by police for scaring rich teenagers?  What was their life like five or ten years ago, and what do they expect it to be like five or ten years from now?  Can they walk to the KFC, or will the police pick them up as if they were Maciej Ceglowski walking around in the wrong neighborhood <a href="http:&#x2F;&#x2F;www.idlewords.com&#x2F;2006&#x2F;08&#x2F;i_spy.htm" rel="nofollow">http:&#x2F;&#x2F;www.idlewords.com&#x2F;2006&#x2F;08&#x2F;i_spy.htm</a> or a black person walking around in a white neighborhood in the US?<p>Why is there only trash on the poor street?  Do people not throw trash on the ground on the rich street, or is there a municipal street sweeping service that takes care of that?  If so, why doesn&#x27;t it clean the poor street?  What&#x27;s up with the lack of safety equipment?  I&#x27;m happy to live in a country where I can still enjoy fast merry-go-rounds, but safety equipment in construction work is super important for preventing accidental death.<p>The <i>derivative</i> and the <i>causality</i> are more important than the <i>current state</i>.
