Easy, the 70's-very early 90's.
The 70's saw the rise of the drug economy, lingering effects of racism, and the systematic dismantling of Black, Brown, Native, and Asian movements. My stepfather utterly refused to sit in a restaurant with his back to the door because the work he did in the community made him a target at the federal level and he knew it. Government aid meant the destruction of the Black family 'cause you couldn't get on assistance with an able bodied man in the house.
The 80's moved a lot of that forward. Most major cities in the 80's became drug fueled war zones. You didn't know if you would step off the porch and end up dead because of a bullet meant for someone else. Lotta families and communities were destroyed by the drug trade back then. On top of that, we had the threat of nuclear annihilation looming over us daily. Racism went from being overt to covert and still kept people of color from advancing. At the end of the decade we ended up at war. When the war in Iraq popped off I had just started college and we ain't know what the fuck was about to happen. Lotta cats was ready to drive over to Windsor, ON if they instituted a draft like Bush threatened to do. If you lived in Cali, the 80's served as a stepping point for gang violence. It was already there, but it got intensified as movies like Colors all but glorified the shit.
I could go on, but I think you get the point, plus I got some work I gotta tie up.
