  • Americans make up around 4% of the world's population, and yet

  • they control over 25% of the world's wealth.

  • If that wealth were shared evenly across the globe,

  • couldn't we solve the problem of global poverty overnight?

  • The answer, unfortunately, is no.

  • Sharing one's one's wealth with those who have less is admirable,

  • and it often helps to relieve immediate suffering.

  • But just sharing existing wealth will never be enough

  • to lift billions of people out of poverty in a sustainable way.

  • To understand why, we need to look at history.

  • This chart shows how world GDP per capita

  • has changed from the earliest recorded history until today.

  • In other words,

  • it's a shorthand way of seeing the wealth of the average human being over time.

  • There are two things we can learn from this chart.

  • The first is that the extreme poverty we see today is not just a modern affliction.

  • For the vast majority of people throughout most of human history, extreme

  • poverty has been all they've ever known and all their children would ever know.

  • The second thing is that, starting around 1800, that suddenly began to change.

  • We're living longer, healthier lives and seeing fewer of our children die.

  • On average, we're better educated, more literate, and better fed.

  • Transportation is faster, safer, and cheaper.

  • And, in many ways,

  • it's been the poorest among us who have benefited the most from these changes.

  • What's made life so remarkably better for the poor wasn't welfare or charity.

  • No matter how you redistributed it,

  • all the wealth in the world in 1800 wouldn't be anywhere near enough

  • to give us the standard of living we enjoy in developed countries today.

  • What happened was the the creation of new wealth on an enormous scale.

  • In other words, economic growth.

  • That's why we're living better lives than our ancestors today.

  • And that's why the number of people living in absolute poverty has plummeted,

  • not just in the last 200 years, but in the last 20.

  • In a way,

  • economic growth has been history's most successful anti-poverty program.

  • But not all countries have experienced this amazing level of growth,

  • which is why many people are still trapped in poverty today.

  • So if we really wanna help the world's poor,

  • fostering economic growth ought to be our first priority.

  • What new policies might help to grow the wealth of developing countries more

  • quickly?

  • And which existing policies are actually hindering that growth?

  • Those are the questions we need to answer.
