Here is the deal, I have special powers and I have just declared you the ruler of the world (if that is too much to handle, then just your present country).
You have been complaining to anyone that will listen that things are screwed up and need to be fixed. For example, too much reliance on fossil fuels, over population, excessive corporate power, racial or economic injustice.
Anyway you are now in charge. What are you going to do? There are only a few restrictions, you can’t propose something which is physically impossible, like reducing greenhouse gasses by 50% in the next year. You also can’t propose something which involves unrealistic changes to human nature. So if your plan requires that no one be greedy anymore it’s not valid. Finally, you can’t propose something that will benefit a select group at the expense of some other group, so no plans that insist that Saudi Arabia sell oil for $10 per barrel.
Over to you…
