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 Chinese mainland had a population of 1.37 billion, an increase of 33.77 million people over the census taken in 2010, meaning the annual growth rate was 0.5 percent.

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.

It's a bit of a lark organised by UK film critics – a gong for the top canine performance at the festival, handed out on the last Friday in the British pavilion. This year the Palm Dog went to Lucky, a Maltipoo – that's half Maltese terrier, half poodle – who plays Dixie in Miguel Gomes' six-hour epic, Arabian Nights. The prizewinner is presented with a toy bone and this year delivered a brief acceptance speech (“woof”) by video link. A jolly time was had by all but an unnamed French journalist felt that the award was “an unwanted intrusion of British silliness” in the glamorous proceedings, according to AFP. “From the French perspective, this is a bit bizarre,” he is reported to have said. “The British are weird.”

These were no lightweight pundits. The eminent historian Margaret MacMillan, in an essay for Brookings in December 2013, said, “We are witnessing, as much as the world of 1914, shifts in the international power structure, with emerging powers challenging the established ones.” She added, “the same is happening between the US and China now, and also between China and Japan”, and also said that “there is potential for conflict between China and two of its other neighbours — Vietnam and Malaysia — as well.”

While both he and Rocky ended up losing their fights on a technicality, Wepner wins in our book for inspiring such an awesome character.

Although foreign trade accounts for a greater share of the economy than ever, the United States is still more insulated than virtually every major competitor in Europe and Asia.

However, Baty said the stabilization of Chinese universities' rankings is no cause for alarm. "Continued investment built on decades of spending, and increased internationalization in Chinese higher education will no doubt ensure China's universities continue to strengthen," he said.

Remedy: Make a budget. If you don’t know how much money you need to live the lifestyle you feel comfortable with, you can’t accurately project whether switching jobs for a $10K pay bump is actually a good deal. Making a pros and cons list when comparing your current job with a new opportunity is also helpful. If the only advantage a job offers is a bigger pay check, you can weigh that against longer hours, a more onerous commute and increased reporting responsibilities. Keep in mind that research shows that increases in happiness based on earnings peak at about $75K. Incomes above this level don’t increase your feeling of well-being on a day-to-day basis. So, if you think a jump up to $85 or $90K will make you feel less morose when your alarm goes off, you might want to look at addressing some of the non-monetary factors in your life that are contributing to your dissatisfaction.

Remedy: The tricky aspect of this regret is that it’s typically rooted in hindsight. Only after you’ve left the job and have moved on to something better, do you start beating yourself up for not making the leap sooner, even if it hadn’t been practical or possible. What you can do is to identify the factors that kept you in your former position as red flags to be aware of in the future and work to line up supports that will allow you to more quickly capitalize on other opportunities as they may present themselves. This could include reviewing and updating your resume with new accomplishments on a monthly or quarterly basis, keeping your LinkedIn account current, building up a contingency fund to allow you to feel less tethered to your current pay check and staying in the loop on industry news and gossip to be aware of where your skills and experience could be of value.
