Prosperity means to thrive. It means to have the appropriate abundance necessary to maintain life and where appropriate grow.

"When its new definition and opportunities are understood, the new ideas of sustainability prosperity are indispensable for both long term financial viability and short term  prosperity." Lawrence Wollersheim
