Back in topic, coal jobs are going away for economic reasons. The mining companies have been moving to automation increasingly, and that reduces the number of miners.
Also, coal is more expensive than natural gas, and guess what? The energy companies prefer a fuel that gives them a larger margin. And that means coal is not in as high a demand.
The side benefits are in health and environmental pollution.
In other words, your objections are not based in hard reality.
Get upset with the mining companies looking at their profit margins. But that will put you in a quandary as well.
It's really not about being upset over the source of energy. Coal, Hydro, wind, solar, nuclear...that wasn't the point.
The point was that there are a lot of people and states that are economically dependent on coal as a source of work.
Take coal away and those already poverty stricken states are even more poverty stricken...and WITHOUT the population to really draw attention.
Now, take coal away and bring in something else that they can make a living on...fine. you aren't screwing entire states over then.
But that's not what happened. Their jobs were taken away...they were insulted for not voting for the people that took their jobs...and they kept being told how privileged they were as they sank even deeper into poverty in areas of the country that don't have the access to programs that help them.
And add to it that now the same party is arguing that you just can't bring manufacturing jobs back for...reasons. And they aren't seeing any hope.
That creates an ENORMOUS backlash.
You add that backlash to insulting them for not voting for Hillary, and you add that to everyone telling them how privileged they are as they are living in poverty...and suddenly you have a situation that is going to breed racism.
It's not the coal that's the problem. It's taking it away while while not bringing replacement jobs to the area...coupled with, honestly, slapping them in the face that's the issue.
If other jobs were put in place when coal was taken, we wouldn't be seen such a horribly racist radicalization of that area.
But now you have poverty+idol hands+anger. The math isn't that hard.
