Obviously the students who are raised in these high-crime areas and surrounded by a community that's significantly harsher are going to be harder for teachers to manage, and I do think this is a very big part of it, but there are some things that clearly aren't related to that(such as equipment and the quality/quantity of staff)
Having disruptive kids also makes educating them much more expensive. Discipline issues chew up a lot of resources and disrupt learning for other students. So you have to spend more to provide equal quality instruction.
And, of course, just because they spend more money doesn't mean they spend it on things that help educating students.
I encourage you to follow this train of thought. It may bring into question some fundamental assumptions in one's world view.

You're looking at county levels. If you look at the parts of cities with poor schools they will have nearly 100% of their students in poverty.
This is a common myth but it's not backed up by the numbers. Poverty is (mostly) concentrated in inner cities and those inner cities typically contain large office builds which pay lots of real estate taxes but send no kids to schools. If you look around different states the highest per pupil spending is by far in the cities. As an example, Atlanta public schools spends $15k per pupil while the surrounding suburban counties are 8-10k per pupil.
