[/quote]If no one is ignorant, there will be no corruption or wrong-doings, because they know it's wrong and they won't (ignorantly) go against it. [quote] This would only be true if people had no opinions. Two people presented with the same facts can come up with different conclusions. Thats why we have more than one person in the jury box. Additionally, people do things that they know are bad all the time. For example: You have two people, A and B. A notices that B has an Ipod. So A takes B's Ipod, even though he knows that this will displease B. Now, because in your world everyone knows everything, B is aware that A took his Ipod. So B gets his revenge.
Now I know what you're going to say: Why would A steal if he knows he will be caught? Answer: For the same reason people steal from stores that use security cameras: people are stupid. And in your wish, does your ignorance include ignorance of the future? Because you run into all sorts of problems if everyone knows everything that will happen.
I'd make the world a worse place, to give people a reason to be grateful. People are pompous pricks, especially in America and other western countries, and are completely oblivious to something so close that it's scary. Give them a taste of genocide and they'll become better people.
I would change... actually, I'm not sure. I'd be afraid of destroying everything. I might think I have a big solution, but I could inadvertently and irreversibly change the world for the worse. You need a wiser man than me.
Wait. That's what I could do. I would change the world by creating a super advanced alien race with an unerring moral compass. They would find Earth. Maybe they could save us. I sure can't.
Lol, attract Mars to us with a larger and stronger gravitational field, make everyone and everything ten times as heavy some nothing could be moved and basically a living Hell.
