What is "a rising tide lifts all boats"

prov. A truly good outcome benefits all.

The aphorism "a rising tide lifts all boats" is associated with the idea that improvements in the general economy will benefit all participants in that economy, and that economic policy, particularly government economic policy, should therefore focus on the general macroeconomic environment first and foremost. The phrase is commonly attributed to John F Kennedy, who used it in a 1963 speech to combat criticisms that a dam project he was inaugurating was a pork barrel project. However, the phrase has been used, more commonly, to defend tax cuts and other policies where the initial beneficiaries are high-income earners.
