Well, and the other issue is the level of education required. WV has gotten a lot of fairly high tech and government jobs, but that's small consolation, at least in the short term, to folks without the education to take advantage of them. Many places face an increasing shortage of jobs that pay a living wage and provide decent benefits without requiring a college education, and when companies that provide those jobs in large numbers in an area close plants or go out of business, it is often devastating to those workers. So, even though WV has increasing opportunities in some career areas and certainly isn't the backwater it's sometimes portrayed to be, it, like many other states, faces a serious issue of shrinking opportunities for those without higher education. So, the initial point that many of the miners may have had limited opportunities to simply switch to another local job with similar compensation could well be accurate. I don't have the data to know for sure, but it wouldn't be surprising to me, and it certainly isn't unique to WV.
