The Enlightment was a time period in which people became intellectually wealthier, in the sense that they overcame their ignorance from the dark ages past. The aphorisms from his Poor Richard's Almanack evidence Franklin was influenced by this concept since:
From the first and second aphorisms, Franklin was born a humble and poor man, pushing him to become frugal (both in money and time), saving every coin and moment he could. Franklin also was a beliver in following what one considers is right, even if none yield their trust in it (Third aphorism). His lack of bad habits and non-existent ambition for great riches paved the way to his success and public acclamation (Fourth aphorism).
