Regressive economists who make a living apologizing for the rich will tell you that making people wealthy is good because a rising tide raises all boats. They obviously do not understand the tides or they wouldn't push that metaphor. Tides, as we know, rise in one place as they drop in another. Some boats go up while others go down.
A simple examination of the income spread in society will tell you which way the tide is flowing. The challenge is to manage the flow so that it goes neither too high nor too low.
