There are many roads to prosperity, but one must be taken. Inaction leads nowhere.

Since I came to the World Bank in 2007, I have argued that we must 'modernize multilateralism.'

We all feel wistfulness or regret about roads not taken.

One always wonders about roads not taken.

When I work with countries struggling to pay for budgets or finance trade deficits, I reflect on how Americans do not spend a moment considering the unique advantages of being able to issue bonds and print money freely.

It is vital that the World Bank Group continually challenges itself to refresh our development thinking. It is vital that a modernized multilateralism be open to new ideas.
