A bad meme -- a contagious idea -- began spreading through the United States in the 1980s: America is in decline, the world is going to hell, and our children's lives will be worse than our own. The particulars are now familiar: Good jobs are disappearing, working people are falling into poverty, the underclass is swelling, crime is out of control. The post-Cold War world is fragmenting, and conflicts are erupting all over the planet. The environment is imploding - with global warming and ozone depletion, we'll all either die of cancer or live in Waterworld. As for our kids, the collapsing educational system is producing either gun-toting gangsters or burger-flipping dopes who can't read.
By the late 1990s, another meme began to gain ground. Borne of the surging stock market and an economy that won't die down, this one is more positive: America is finally getting its economic act together, the world is not such a dangerous place after all, and our kids just might lead tolerable lives. Yet the good times will come only to a privileged few, no more than a fortunate fifth of our society. The vast majority in the United States and the world face a dire future of increasingly desperate poverty. And the environment? It's a lost cause.
But there's a new, very different meme, a radically optimistic meme: We are watching the beginnings of a global economic boom on a scale never experienced before. We have entered a period of sustained growth that could eventually double the world's economy every dozen years and bring increasing prosperity for - quite literally - billions of people on the planet. We are riding the early waves of a 25-year run of a greatly expanding economy that will do much to solve seemingly intractable problems like poverty and to ease tensions throughout the world. And we'll do it without blowing the lid off the environment.
