Both good things when it comes to jobs. More humans to do more productive things, and more profits. Not good when it comes to national security. There is more to geopolitics than your simple view of jobs.Fewer human jobs and higher profits.
But wait - how is that possible? Isn't China part of the Paris Climate Agreement?? We're not part of the agreement and our emissions are going down - they are part of the agreement, so surely their emissions are going down, right?We stop using coal and moved to NG and other power source. Less coal is good, right? Well, that means less demand from the US, which drives down coal cost. That means China can burn even more coal even more cheaply.
Guess what happens when we move off oil? Chinese would love that. Drive up costs in the US, drive down China's and makes them even better for manufacturing and distribution.
