"The U.S. is again a source of strength in the world economy, only five years after it was the center of a global crisis. This has not happened by accident," said Lew in an opinion piece published by the Financial Times. "In many parts of the world, such as Europe, growth is too weak to drive job creation, and it is critical to take steps to bolster private hiring."
