"A rising tide lifts all boats" is a metaphorical expression that means that when there is overall improvement or progress in a certain area, everyone involved in that area will benefit from it. The phrase is often associated with economics, and it is used to suggest that an improved economy will benefit all participants. The phrase was made famous by John F. Kennedy, although it is often attributed to him mistakenly. The phrase has also been used in recent years to highlight economic inequality, with some arguing that the rising tide will lift some boats but not others. In the workplace, the phrase can be used to suggest that when one person improves, it can have a positive impact on everyone else.
