The shitification of US big cities began a* very long* time ago. The bad areas back in the last century were kept in check by politicians and real estate agents, much like happens today in rural America. Urban crime was concetrated in black neighborhoods. Slowly, beaners began taking over the lower cost white areas and ruining them. Decades ago, the federal government began shipping ghetto dwellers into better areas, in a foolish attempt to help those that wanted no help, they only wanted gibs, things went to hell within years. What we see today is the slime completely taking over. Now Chicago has their first female black mayor. That must be the answer to it all! All the shit rolls downhill in today's American cities.
