Vietnam's prosperity has been an upward trajectory for years. Rapid economic growth means the country's GDP per person now stands at just over $3,750. That's still lower than its regional peers, Malaysia and Thailand. But Vietnam has one particular strength that could help it close that gap further. It's education system. Several studies have shown that the caliber of teachers in Vietnam is far better than in other countries. And that's not because they are better qualified, but because they're simply more effective at teaching.
