a rising tide lifts all boats(Proverb)

Benefits provided to a few may lead to conditions that are beneficial to all.

A rising tide lifts all boats

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.
