One of the very few things that Barack Obama was right about is the fact that the world is in better shape than at almost any time in its history. Yes, we have problems, but things are generally pretty good. Globally, people are healthier, safer, live longer, and have more free time than they ever have before. We're also witnessing a planet where world peace is on the rise, global poverty is on the decline, and starvation is in freefall.
In short, it's a good time to be a human being.
Of course, there's work to be done and left-wing policies can always drag us backward - just look at Venezuela or the Middle-East - but if you take in the big picture you'll see we're in pretty good shape.
