This a little theory I have...a few of my friends disagree with me. I believe it's partly due to technology and the procrastination that comes with it. There's almost 5 billion people on the planet using smartphones, that represents 60% of the earth's population. And the number of users is only going to go up.
People spend more times on their smartphones, be it functional 9-5ers or "career criminals". Let's say a guy makes a career in crime, he's probably going to be on his phone a few hours a day not committing crime. And some people use smartphones to broaden their horizons and learn new things.
For all the crazy things going on in the world, there's been no better time, in history, to be a human being than it is now.
