It's simple, yes we might have less violence and your stats seem to make sense.
However, the reason you are right is because we are being more controlled by, I don't know world bank, countries, laws.
Today in Turkey they want to give the president the power to turn off the internet at will for 24 hours. There is news like this every day, ways to get more control and power over people.
There are 1 million camels in Australia, the government thinks that that is to much and they pay people to shoot them. So, one milion camels is too much for a whole continent but there is nothing wrong with having 8 billion people on earth, destroying just about everything, that is ok?
We have no choice in what is happening around us, most people I know would want their country to stop importing oil and find a greener alternative. This day an age that wouldn't be too hard. So why aren't we?
That is not in your equation!
We are destroying our oceans, atmosphere, finally the republicans are willing to talk about climate change, but all is still weight around money and cost.
The monetary system is broken and it is global. One little change effects one way or the other the entire globe.
If you ask me it all is hanging in a balance that is controlled by a few wealthy. And it is hanging on very thin strings these days.
