If you could invent something to help mankind, what would it be?

If I were to invent something to help mankind I would invent a new system of government. One that allows for healthcare to be accessible to everyone and one that allows education to be prevalent in all parts of the world. The world offers enough resources to help everyone, so that no one should have to go hungry. Also, the world offers resources that could cure diesases, this should be available to all people no matter how much money they have. I feel that if the world were more integrated and was not run by leaders making decisions for financial benefit than all people would benefit in many different ways. If the system allowed for things to be not tied to money when it benefits all people the world would be a better place. For example, building a more green world (electric cars, houses, hospitals, medicine, surgeries, etc) should be made easier because all of the materials and efforts should be available without monetary funds.
