Here is an example of Malcolm Turnbull's reasoning on coal mining which
caused him to be dumped by the NSW Laberal Government:

IMO, it is reasonable to curtail the opening of new coal mines when existing ones are financially struggling due
to oversupply which in part is due to China economic sanctions.

This is not rocket science regardless of whether one is Left or Right;

There is the marketing triangle of supply, demand and price.
Increase supply and/or reduce demand and the price goes down !!!

The Lefties want to close down coal mines, the Right want to open more and reasonable Malcolm in he middle
is saying "don't open any more but maintain what we've got" reasonable eh?
