Second, we have a different view of failure than many other nations. The relatively low social and legal consequence of failure allows Americans to stand back up, shake off the failure and try again. Think about how many restaurants there are and the number that will fail within a year or two. It is millions of failures annually. In Germany, for example, if a business does not notify its creditors 30 days before running out of cash, the president can go to prison. In the US, a business has no requirement to ever notify their creditors at all. We seem to see failure as a consequence of taking a risk, not as a scarlet letter. To never fail, is to never try.
If you combine the two, we have a society where people not only have a better opportunity to discover their passions, they feel much less encumbered by the prospect of failure than in other countries. Passion drives innovation, creativity, persistence and the competitive spirit. Can you imagine Apple, Microsoft, Walmart, Amazon, MacDonald's or any other 'huge success' without a passionate, risk-taking founder? Even Subway has such a story.
The product of our education system may not do as well on tests as their peers from other countries, but when they get into college and choose a major, they are more likely to be passionate and self-motivated and excel in their chosen curriculum.
Our educational system needs help, there is no doubt. Since my grade school days, funding for the arts has completely disappeared. Schools are run down to the point of being shameful. But the key ingredients that produce greatness are still there.
