I wonder how long until someone builds a high speed commuter line into the heart of WV from DC. There is probably an obvious reason not to, but from my west coast perspective it seems like a good idea.
At the same time, much of WV's private economy was centered around extraction and manufacturing, both of which have declined over the decades.
There's a big highway under construction into the center of WV, currently called "Corridor H", that is intended to link up with 66, a major artery in and out of the DC metro area.
I think it's unlikely that high speed rail gets built in that corridor any time soon, simply because high speed rail in general seems unlikely in the U.S. right now.
And unlike some other regions known for mountains (like New England) there are no (relatively) wide valleys between them.
It's wild, beautiful, and absolutely awful for building even a decent sized town in. It's why the few cities in the states are at the far edges, and even they are hilly. It's also obviously terrible for building transport infrastructure to get anywhere quickly.
I grew up in MD and spent a lot of time in WV. It's a beautiful state with a lot of wonderful people. It has a modest crime rate and a murder rate typically 1/3 lower than the US rate. And of course as noted it's quite poor relatively speaking. Sub par economic outcomes is one of the long-term constants of WV. You will often notice the difference in the quality of the roads immediately when you cross into WV from MD or VA.
Here's one big reason why that high-speed line will never happen from DC to eg Morgantown or Charleston WV: the population of West Virginia hasn't increased since the 1930s. 1.8m people in 1935, 1.8m today (and falling). The demand just is never going to be there, given the extreme cost to build infrastructure in the US.
I'm not sure I could tell you if I was in (non-coastal) rural MD or rural WV (same as I'm not sure I could tell you if I was in Fairmont, Cumberland or Winchester).
Median doesn't tell me much because it doesn't describe the skewness of the distribution of incomes. Without looking, I bet that both: 1) max income is higher in MD than in WV 2) there are more people at higher incomes in MD than in WV
So I looked it up for MD [0] and WV [1] and while they don't really help with my conjectures, MD has a higher per capita income ($24,774 in WV vs $39,070 in MD) and lower poverty rate (19.1% in WV vs 9.3% in MD).
Also interesting to note from those sources that they have basically the same retail sales per capita and rate of persons without health insurance (although MD has about half the disability rate).
