Aight I feel where you coming from and I do not agree. It's a big reason people in poverty are profiled and looked like criminals. It's a common belief that keeps people in poverty feeling like something is wrong with them.
You're on the right path but you're coming to the wrong conclusion.
Poverty DOES lead to these kinds of outcomes. There are studies on this showing the links:
How Poverty Drives Violent Crime.
Poverty, true poverty, leads to people having to steal or kill just to eat, and do drugs to cope. This means the people with access to those drugs will use that as a means to feed themselves, thereby perpetuating a self-sustaining system. Poor people feel they need the drugs to escape their realities (or even injuries and sicknesses, because they can't afford healthcare), so they'll do ANYTHING to get that high, including prostitution and violent crimes seeking the money.
Gangs (black street gangs specifically) are the result of being abandoned and terrorized by the government. That system will utilize the method I mentioned above to sustain itself; there's a reason the pimps in LA used to be mostly Crips. They sold drugs and pimped women to make money because they felt they had no other avenues to feed themselves. Tookie stated they started the Crips to protect the community from the law and other gangs. The problem with that is, once they got a little power, they turned it on the community.
This is well documented in other countries outside of the US. In neighborhoods stricken by poverty, there is almost ALWAYS a rise in drugs, drug abuse, prostitution, and street violence. They are connected at the hip.
I get what you trying to say; I'm from the hood myself, but I didn't get involved in these things. I've been stopped and frisked by police just based on where I come from, and that was dehumanizing. But the truth is poverty is linked to those issues in the hood, and they cannot be de-linked. There's a reason affluent neighborhoods are almost always linked to white-collar crime and not street crimes-- they don't need to do the things the people in our hoods needed to.
