Ten Optimistic Trends – Part 3
This is the last installment of Optimistic Trends. See Episode 121 for the beginning.
9 – The Long Peace
In 1946, there were about 50 countries. Today, there are about 200. As decolonization and striving for independence have quadrupled the number of sovereign countries, one would expect that wars and military conflicts between countries would steadily increase over the same time. But that’s not what we see.
Despite our short-term memory fixating on Russia’s invasion of Ukraine, the number of interstate wars worldwide has decreased since the end of World War II. The rate at which those wars are decreasing also seems to be improving.
This is mainly due to how intertwined countries have become in their economic and wealth-building pursuits. Armed conflict is bad for everyone. Countries that are furthest behind economically are largely those that have been torn apart by internal violence. And aggression across borders is destructive to the pursuit of prosperity.
Countries have realized that we will all get ahead better and faster if we can all get along. The decline of wars is an inarguable positive.

10 – A Safer World
Over the last one hundred years, the chances of someone dying in a natural disaster have decreased by almost 99%.
Technological advancements in infrastructure and early warning systems have allowed us to survive, avoid, and evade more natural disasters.
The largest disasters over the last two decades have occurred in the developing world.
- 2004: The Indian Ocean Tsunami killed 230,000 people.
- 2010: The Haitian Earthquake killed 223,000 people.
- 2008: Cyclone Nargis, a Category 4 Storm in Myanmar, killed 138,000 people.
Here’s a comparison illustrating just how good our technology has become at helping us avoid death by natural disasters. Take another look at the last example above. Now consider this:
- 2010: Cyclone Yasi, a Category 5 Storm in Australia, killed 0 people.
Natural disasters still kill many people for no other reason than there are more of us. But the deaths per 100,000 have dropped precipitously. The Great Enrichment will eventually help pull the developing world into the middle class, and the same technological advancements that keep countries like the U.S. and Australia safe will also be widely deployed in these countries.
We look forward to an ever safer world.

Optimistic Trends Everywhere
Across the spectrum, the world is heading in the right direction. That is not to say there are no hiccups or that you can’t find a few statistics that trend in the wrong direction. But this proves that we can fix problems that arise through human ingenuity.
In a world where everything is negative, I hope that has encouraged you to see how many things are going in the right direction.
Many of these advances have been spearheaded by the best businesses in the world, or those same businesses have taken advantage of them for additional benefit and gain. As we move into an uncertain future, will you participate in those advancements? Or are you going to stay on the sidelines? It’s your choice.
