How do you think 2015 will be for you? If you’re typical, you’ll be pessimistic; and, if you’re typical, you’ll be wrong. Only 21 percent of Americans agree with the proposition that “life for our children’s generation will be better than it has been for us” — 76 percent disagree.

Well, barring some unforeseeable calamity — what Nassim Taleb would call a “black swan,” or Donald Rumsfeld an “unknown unknown” — the 76 percent are mistaken. The next generation of Americans will lead healthier, happier, more fulfilled lives than the present one.
