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 we at The BostonConsulting Group believe that the current dip in China’s growth will not endureand that, under Xi’s leadership, China’s economy is destined to continuegrowing at a rapid clip. In fact, we are confident last week’s reforms willcontribute mightily to China’s growth between now and 2020. We stand by our base case forecast that China will deliver$4 trillion in growth over the next decade and combine with India to deliver a$10 trillion prize — an economic powerhouse driven by booming middle classconsumption and growing overall optimism. No one can perfectly forecastthe future … and in our book we describe scenarios where growthslows. But we remain optimistic and positive about China’s future.

But the UK courts may land a heavy blow on ride-hailing app Uber. In 2017, the California-based company failed to persuade an appeal judge that two of its London drivers are independent contractors. In 2018, the test case will go to the Court of Appeal and possibly to the Supreme Court. If Uber loses the case and is told to assume the responsibilities of an employer, the implications will ripple far and wide.
