A rising tide lifts all boats

"A rising tide lifts all boats" is an aphorism associated with the idea that an improved economy will benefit all participants and that economic policy, particularly government economic policy, should therefore focus on broad economic efforts.

The expression has also been used to highlight economic inequality, with the sentiment that the rising tide is primarily lifting expensive boats such as yachts, by politicians including former U.S. Treasury Secretary Robert Rubin, British Labour Party MP Ed Miliband, and New Zealand Labour Party MP David Parker.
