It’s an election year, and candidates can’t stop speaking about our country’s problems (which, of course,
only they can solve). As a result of this negative drumbeat, many Americans now believe that their children will not
live as well as they themselves do.
That view is dead wrong: The babies being born in America today are the luckiest crop in history.
American GDP per capita is now about $56,000. As I mentioned last year that – in real terms – is a
staggering six times the amount in 1930, the year I was born, a leap far beyond the wildest dreams of my parents or
their contemporaries. U.S. citizens are not intrinsically more intelligent today, nor do they work harder than did
Americans in 1930. Rather, they work far more efficiently and thereby produce far more. This all-powerful trend is
certain to continue: America’s economic magic remains alive and well.

你们觉得有道理吗？
