If you could change 3 things in the world
I don't mean like sudden change that would puzzle everyone. I mean change as if it had always been that way with the stipulation that there would be no retro consequences for the changes. You wake up tommorrow minus any feelings based on the three changes but everything else would remain the same.
All people would speak the same language.
All people would be the same race.
There would be one worldwide religion based on a single deity and no prophets. Take it or leave it.
That would be the starting point. Things could get better or worse from that point.
We had this conversation at a family Thanksgiving gathering and it is amazing how controversial it can be.
