Andrew Syrios writes in today’s Mises Daily:
After all, isn’t it true that the most hard-working and intelligent people tend more to go to college? This is not a nature vs. nurture argument, the factors behind these qualities are unrelated to the discussion at hand. If one grants, however, that the more ambitious and talented go to college in greater proportion than their peers, Mrs. Clinton could have just said “the most hard-working and intelligent earn nearly an estimated one million dollars more than their peers.” I think the presses need not be stopped.
For one thing, the Census Bureau estimate includes super-earners such as CEO’s which skew the average upward. Although some, such as Mark Zuckerberg and Bill Gates, didn’t graduate college, most did. This is why it’s better to use the median (the middle number in the data set) than the mean or average. It’s also why Hillary Clinton and other repeaters of this factoid don’t.
