But we could, if our leaders were responsible. The Mormon church for a long time exercised a principle called the law of consecration. Under this law there was no currency, only the trading of goods and services. Right now the world has enough resources for the entire world to live well and without any poverty, if it was spread evenly and justly. If we allowed a perfect person like Christ to decide where everything goes, then there would be no more hunger and poverty. This would also require humanity to be humble enough to sacrifice their decadence, which is why we don't live under this law now, since we aren't ready for it.
