I am not an economist but I can see how this will help American in several ways.
First the dollars sent to the middle east (and used to support terrorist) will remain in the US.
Second it will make America more energy self sufficient and there will be less chance of the Muslims in the middle east to use oil to black mail us into doing what is against our national interest.
Third more jobs.
I am sure there are more good things to come out that (not counting environmentalist’s heads exploding)
West Virginia had second highest GDP
WASHINGTON - West Virginia had the second highest growth in gross domestic product (GDP) of any state in the country during the first quarter of 2017, and Gov. Jim Justice attributes the climb to the bounce back in the coal industry.
Mining grew by 21.6 percent nationally, according to the U.S. Department of Commerce report, contributing to growth in 48 states. That made Texas, West Virginia, and New Mexico the three fastest growing states, growing at 3.9 percent, 3.0 percent and 2.8 percent, respectively.
"I know the coal business like the back of my hand and the current spike in the coal market was one I saw coming, and our state Legislature refused to listen," Justice said in a news release. "If you go back to the October 2016 debates for governor, I said that coal would rebound and that our severance tax collection would go up. Some people laughed at the time, and they were totally wrong."
The governor's office also reported that a new Reuters analysis shows U.S. coal exports have increased more than 60 percent this year due to soaring demand from Europe and Asia.
Delivering promises Bigly.
