You’re also assuming those who are good at mining coal could somehow instead be good at both protecting the planet AND making as much money. That’s seldom the case.
I think it's not that straightforward of a situation.
Further there is a weak link between resource extraction an long term economic growth. It requires a huge investment in resources and education that becomes worthless after the resource runs out. Just look at West Virginia to see the long term boons from coal mining.
I don't understand what you're getting at. Compare the life of an average person in West Virginia today to the average person in West Virginia before coal mining and the person today is immensely better off. Technological improvements are the payoffs from investment.
