Do you remember Franklin D. Roosevelt's 2nd Bill of Rights. Well, I'll start with those, and then probably make all the oil executives pay for all the damages they caused to the world, and then send them to jail for a very long, long, long time. All the workers of said oil companies will be fine, give them public works jobs until they can find something else. Also, while we are on that subject, transfer all people on unemployment and not actively seeking a job within the next month would be immediately transferred to public works until they can find another job. If they refuse, then they don't get the unemployment checks. And, simultaneously, negotiate with the unions of all workers of the world to set up a system of governance that prevents lazy workers from being defended from said unions. Also, establish a new world currency, and invest in nuclear energy until a more efficient green energy is found (in case you're wondering, I would also invest heavily in green and nuclear energy R&D). Finally, remember the space program, how we were going to send a guy to Mars, and colonize the moon, and other stuff like that, well say hello to space program Mk. II.
