Federally-funded farm subsidies are a huge deal to rural people in Midwest. Those are largely possible because mostly rural states like Kansas, Nebraska, Oklahoma, and the Dakotas have senators who strongly advocate for those deals.
Appalachians don't have the type of land that benefits from those subsidies, and they don't have enough clout to get an equivalent type of economic benefit package. The TVA was the last major economic project the feds funded, and it was hugely popular because it did actually improve the lives of people there. Better federal representation at the Senate level wouldn't solve every problem, but it could definitely alleviate some of the pain.
