Many parties start up with the best of intents, and when they get into power, they get phone calls from the emotionless and monstrous Guardians of the Inexhaustible Treasuries in London and New York. They inform the recently politically victorious of the Facts of Life. I.E. "If you carry through with that election promise, your interest rates are going up to 30%. Look at the screen of your jurisdiction's bonds. Now watch this!" "Oh. Ok.."
Then the well-meaning and sincere in all respects politicians have to backpedal, and ideological people who know nothing about The Facts of Life call them sellouts and hypocrites etc. Being out of power, like Elizabeth May, they can say anything they want. We have free speech after all.
However even if Elizabeth May were to become Prime Minister, she would have to say, "The pipeline is going to be built."
The only fault of Syrizia and the Alberta NDP was that they thought they could change anything. Being out of power, and out of contact with the Guardians of the Inexhaustible Treasuries, they had no way of knowing any different. Neither did the people who voted for them.
People ought to realize it is their economic choices and not their political choices which determine who gets rich and who stays poor. If they can overcome their personal selfishness and greed, and actually change their behaviour (like saving money instead of spending it and buying bonds from the Guardians of the Inexhaustible Treasuries, thus taking away their sword-of-Damocles power), maybe we shall see some change in this world.
Not until.
