Yeap, can confirm. Kentucky has a program that is desperately trying to get new teachers and inject fresh blood into its rural schools. It sort of works. Young, new, teachers go teach in BFE for the required few years and then get the hell out because teaching in rural Redneckistan is depressing. You watch the kids either give up or get out as fast as they can. They did try to get non-white teachers into some of the rural districts, but none took the deal. One of the better rural counties that I do some work in, Breckinridge, has fewer than 500 black people TOTAL in the county; most of those are military associated with Fort Knox. Grayson county, where I do a library program once a year, is even less diverse. But the big numbers are as below:

The median income for a household in the county was $27,639, and the median income for a family was $33,080. Males had a median income of $27,759 versus $19,302 for females. The per capita income for the county was $14,759. About 13.90% of families and 18.10% of the population were below the poverty line, including 24.10% of those under age 18 and 15.70% of those age 65 or over.

Grayson County, btw, 80% Trump.

There are a thousand Grayson Counties out there. And every time I go down there I am both cheered on by the ways people band together to exist in a changing world, and appalled that people I consider my fellow Americans are being left behind. 15K Per Capita Income. 1/4 of the kids living in poverty. And they all voted for Trump who is arguably going to make their lives harder.
