The root causes of gang violence in the inner city?

There's just one; money.

Competition over drugs, that gets you the money. Competition over women, that you get with the money.

An inner city youth gets gunned down, the cops release a statement saying there was a dispute over drugs or a woman, or both. But underneath that, it's money.

An inner city youth gets arrested for killing another inner city youth. He may say the dead kid "disrespected" him. That disrespect came from a dispute over drugs or status within a gang, or a woman. But underneath that, it's money.

Money brings respect and women. Access to drugs, which brings the money, comes from status.

To get the money, you've got to have status and respect. To keep the status and respect, you've got to get the money. To get the women and keep them ...

You get the idea.
