Use prosperity to refer to the state of being successful. In the US, the decades following World War II were characterized by rising prosperity, with large numbers moving into the middle class.

Prosperity usually means the type of success that comes from having a lot of money. Our modern English word derives from Middle English prosperite, borrowed through Old French from Latin prosperus "favorable." The Latin word also means "fortunate," and the word prosperity does have an element of good luck.
