It is easy to say "we need to do this or that" to make a better world, but in truth you can only say "I". "I" is all you have control over and your better world cannot be acheived unless the entire world changes and that is not likely to happen. There will always be those who covet other's property, life or anything and that will only change when money is no longer needed or used anywhere in the world. The human animal as a whole doesn't have the capacity to change much at all.
