It really would. All current economic systems would look absolutely stupid compared to what we would have. However, people would still be subject to pride and greed. It's human nature. We would still need to have a government to protect people's rights, and a religion would be needed if it is true. Religion isn't here to control people. People will practice religion because they believe in God. If we could all determine truth, God would not cease to exist or pop up if he wasn't there. There are two possible cases of what would happen. God exist or doesn't. If he does, we would have religion. If not, we would not have religion. Of course, that religion or lack thereof would cause 1 universal moral code IF people weren't the selfish, prideful beings they are. There would most likely be a level of opposition to everything, sadly.
