Reclaiming The American Dream VI: The (Other) Lessons of Khan Academy

Howard Husock
This article is more than 6 years old.

To say that Khan Academy has important lessons to offer is to state the obvious. The Mountain View-based internet teaching institution—which has grown from founder Salman Khan’s individualized YouTube math lessons for his 7th grade niece to a worldwide phenomenon—offers thousands of free, plain-spoken online courses, from algebra to biology. But there are even broader lessons to be taken from the astounding success of Sal Khan, winner of the Manhattan Institute’s $100,000 2014 William E. Simon Prize for Lifetime Achievement in Social Entrepreneurship. Indeed, the lessons extend well beyond education

The story of Khan Academy’s start and growth is dramatic. Sal Khan, New Orleans-born and MIT-educated, was working in the finance industry as a hedge fund analyst when, in 2004, he learned that his niece, Nadia, needed help with algebra. He began sending her his own clear, step-by-step illustrated lectures (Khan himself did not appear) via YouTube. That allowed other web users to use the same lessons. The teaching of Khan—a complete outsider to education or education reform—went viral, ultimately catching the eye of Bill Gates, whom Khan learned was helping his own children with lessons first meant for Nadia. Khan eventually attracted $15 million-plus in philanthropic support from the Bill and Melinda Gates Foundation, Google , venture capitalist John Doerr, and others accustomed to the idea that radical newcomers might be worth investing in. Such funding allowed Khan to give up his day job and start Khan Academy, with a forthright, undeniably ambitious goal: a free world-class education, for anyone, anywhere.

But economists generally expect the momentum of the recent past to resume and continue once storm distortions abate. The 45 economists who responded to The Wall Street Journal's latest monthly forecasting survey saw the jobless rate falling to 7.8% by next June and 7.5% by the end of 2013. Some say job growth could accelerate from its slow pace. 'I think businesses are going to have to hire,' said Bob Baur, an economist with Principal Global Investors.[qh]

Another common path to job loss is the habitual obsession that many employees have with social media. Some companies have taken measures to monitor or limit their employees’ social media use, while others have blocked these sites completely. So beware: spending too much time on social media or other websites not related to your work can cost you your job.
"I'm always amazed at how many people tell their co-workers about their job search," Kay says. "That's one of the worst things you can do." Ideally, you wouldn't tell any co-workers, but you may have to if you want them to serve as references. In that case, Kay says, "you need to pick people who you really trust, who don't have a hidden agenda and who won't let it slip."

‘Jeopardy!’ This game show celebrated the 50th anniversary of its debut (broadcast on March 30, 1964), and proved it can still not only stump viewers but also surprise them. That’s not just because the host, Alex Trebek, briefly regrew a mustache after 13 clean-shaven years, but also because some contestants showed they could still rile an audience. This year, it was Arthur Chu, who introduced a blitzkrieg style of gamesmanship that provoked a cyber hate-fest. His strategy was thrilling and certainly effective: he came in second in the Tournament of Champions. (Ben Ingram, the nice guy, finished first.)

'Inside Llewyn Davis' finds the Coen brothers, Joel and Ethan, in a hauntingly somber mood that somehow translates into memorable drama. I think my review should have made it clearer that this elegy for a casualty of pop culture is a special taste; some of it is fairly glum. So much of it, though, gets to something stirring by way of Oscar Isaac's phenomenal performance as a self-defeating folk singer fatefully dedicated to his art.

With the majority of professional advisors (myself included) preaching the benefits of global diversification to their clients, 2014 looks more like a draw than an outright victory in the harsh light of December’s low winter sun. Consider the fact that, through last week, the MSCI World Index gained just 2% on the year, with nearly 5% drops for both the MSCI Emerging Markets index and the EAFE index of developed markets outside of the United States. Ironically, the single best-performing foreign market in the world, the Shanghai Composite of mainland Chinese equities (up 45%) is the only one that U.S. investors could not actually put their money into.
