Its just a realization that we must all come to. Petrol was always heavily subsidized, but in the 50s it became apparent that subsidies would not be enough. By the early 70s an endless stream of bailouts started taking place at increasingly greater cost. We know them in camoflaged form i.e., change in currency basis, embargos, production easing, cartels, wars, trade sanctions, austerity, bank bailout, rolling black outs, gas leaks, terrorism, the switch to empire (totalitarianism,) secret energy policy, secret law, false flags, reducing wages, increasing personal debt, reducing standard of living, declining security, loss of safety net, loss of basic freedoms, loss of privacy, loss of a voice, loss of a functioning media, the rise of lobbying, rule by money.
A great sign that these bailouts had come to an end would be ending the insistence that oil or petrol be traded for dollars and the end of petrol subsidies. At the same time its a trick to link petrol to bits of the safetynet through a tax because that would keep petrol energy alive along with its problems.
And lets be very clear that the new Trump tarifs are primarily an attempt to shield domestic petrol from Chinese solar panels- its not dumping its just the real cost advantage of solar. Its also the US issue with China. That won’t stop rest of the world from cutting the cord on petrol (and its an overseas dependent industry) or stop even the US. He is hiding behind jobs, human shield style the terrorizing employers always hide behind the job creator bs.
