Excellent observation.   From my perspective and experience, the vast and endemic poverty that exists in Mexico is not a natural occurrence.  The Church, sadly, has been complicit in this process.  Mexico is owned by about 100 biological families.  Their absolute power requires the tacit protection of the Church.  Mexico should be prosperous.  It has all the necessary ingredients for a sound economy.   Yet it remains a place that people are trying to leave.  The Church does have a role here.  It can let the Mexican Elite know that it is past time for them to release their control and democratize Mexico.  And those in America who prosper because of these conditions should be told in no uncertain terms that our Catholic Church is here to spread the message of Christ---love you brother.
