Widespread economic prosperity typically reaches all citizens of a country or region. A country cannot benefit without all of its citizens somehow benefitting, in the same way that an incoming tide will lift all boats including both the behemoth cruise ships and the tiny canoes.

Occasionally, the adage also may be used when referring to entire groups benefitting from a change in circumstances, particularly an influx of resources that seemingly might reach only individuals. I have heard co-workers respond to their co-workers receiving large sales commissions by saying, "a rising tide lifts all boats," implying that the increase in business for the company will expand the total opportunities for the company (and thus all employees). In this use case, clearly it is understood that the "rising tide" does not lift all boats equally.

Critics of this proverb may dispute its veracity claiming the phrase is erroneously used to justify any type of deal or arrangement that seems to benefit the few, but typically the expression is used with optimism or as a form of mild celebration by leaders, or members of the group themselves.

The proverb is often attributed to John F. Kennedy after he used it in a 1963 speech disputing the claim that a dam construction project had too much pork (wasteful spending). Kennedy's speechwriter (Ted Sorensen) revealed that the New England Council originally used the phrase, which Kennedy borrowed regularly.

A similar phrase is "to grow the pie," which means to make the entire set of opportunities greater, presumably so that everyone can appreciate a larger piece of pie, even if their percentage of the pie does not change.

Do you share the sentiment that broad economic prosperity reaches all?
