No more Oligarchies, GMOs, Big Pharm, Big Pesticides, Big Oil, etc. The government has to prioritiize benefit for people and to protect the environment ahead of profit, and tell the truth.

You don't want to give me that kind of power, not even for a day ???

I reckon I'd ban the private practice of law. All legal cases, criminal, civil and family, everyone gets randomly assigned lawyers from a pool of specialists, all paid by the state. Everyone, from the homeless vagrant to the multinational corporation, gets the same level of representation. Justice no longer for sale.

I want to say I would demand world peace, end of a nuclear threat, disease, egos, want and ignorance...but to be honest I'd probably make it law that I had tons of money and didn't have to work and that the best people on earth (bar none) were chubby gingers from NW England

I cannot be trusted with this power.
