Today's poverty level is %25, what do you think that number was before the 1965 Civil Rights Act.
You can't help to have a bad attitude when you have been at a disadvantage the whole time your people have been in a country.
Do you deny that inner city minorities were at a disadvantage starting in 1965?
Please provide us with your definition of "poverty."
I think they were at a disadvantage BEFORE 1965 too. I know there were many more prosperous minorities in the inner city before 1965 (they left for the same reasons the whites left the inner cities). But there was always an underclass of poor in the inner cities. And not just "minorities," if by that you mean African-American.

I don't think my mother-in-law's family in a town named Mine 7, PA or something like that had a great attitude either. When she got tired of saving flour sacks for recycling into washcloths and canning food so the family would have something during winter, she left. Those eastern european coal miners in PA were at some disadvantage too. She left to do piece-work in NYC and send some money to her mother. I guess she had a bad attitude too, but that didn't stop her from trying to do more than just survive.
Again, so what? Do you have a point to make? What is it?
