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.

With the release of his book Conscious Capitalism, Whole Foods (WFM, Fortune 500) CEO John Mackey got business leaders thinking about a compelling idea: Companies work best when they create value for all their stakeholders -- not just investors. According to Mackey, key stakeholders include customers, employees, suppliers, society, and the environment. Highlighting companies like Costco, Southwest Airlines (LUV,Fortune 500), and Google (GOOG, Fortune 500), Mackey demonstrates that thinking about more than just the bottom line builds stronger and more efficient businesses.

Thus it's rather a shock when you first encounter Nick D'Aloisio striding into London's Bar Boulud restaurant, firmly shaking hands and proceeding to outline his entrepreneurial vision. To imagine him in person, picture a Silicon Valley CEO blessed with an easy manner and 97th percentile media skills. Picture a guy who can confidently expound (while maintaining steady eye contact) on topics ranging from Noam Chomsky's theories to the science of neural networks to the immigrant mind-set to the Buddhist concept of jnana. And now picture this fellow trapped inside the gangly body of a British teen who might easily be mistaken for a member of the pop boy band One Direction-clad in a hipster T-shirt beneath a fitted blazer, hair swooping over his forehead, taking bites of a cheeseburger between bold pronouncements.

No. Wall Street strategists’ predicting that the US government’s 10-year borrowing costs will climb above the 3 per cent mark in the coming year is as much a staple of the Christmas period as awkward office parties. This year the forecasts look more likely to be fulfilled, given a withdrawal of quantitative easing and the US tax cut. However, the seismic, secular forces pinning down both inflation and long-term bond yields remain in place and are still underestimated. The Federal Reserve will raise interest rates at least three times in 2018, but the 10-year yield will not breach 3 per cent.

补救办法: 做预算。 如果你不能估算需要多少钱才能过上令你感到舒适的生活,你就无法确切地知道为了1万美元薪水而换工作是否真的划算。在比较新、旧工作时,列出各自的优缺点,这会对你很有帮助。如果新工作只是薪水更高一点,那么你可以比较下这个工作是否要求更长的工作时间和完成更多的工作任务。请记住,调查表明:年收入在7.5万美元以内,幸福感会随着薪水的增加而增加,但是一旦薪水超过这个水平,幸福感的增加便不再明显。因此,如果你认为薪水增加到8.5万或9万美元会使你更加快乐,这时你或许应该着手解决生活中那些与金钱无关而引起的不快乐。
