Not that anyone will see this but regarding this comment's siblings:

It seems like you don't understand the metaphor unless you each mean to imply that The Economy goes through frequent regular cycles of significant expansion and contraction where every expansion reaches a consistent, predictable high point before contraction brings it back down to a consistent predictable low point.

But it can still accurately represent the people who are "left behind" in the economy. You cannot just say "Ah yes, the tide is going up. Therefor everyone is safe and dry in their boats as they rise with the tide" as an excuse to ignore people who need help.

Those too. You put enough extra length in the anchor chain to make sure of it. Did you think that moored boats all sank when the tide came in?

For that matter, what about the wrecks on the bottom of the ocean, and the survivors bobbing on the surface?

>What about boats that are anchored or moored?

Well how else were you going to wash the sides down?
