Tbf, that was also true of the French Revolution. Robespierre was a well-to-do lawyer, Santerre (fellow Jacobin & jailor of Louis XVI) was a rich brewing business magnate, Saint-Just (even more bloodthirsty than Robespierre, nicknamed the 'Archangel of Terror') was from minor nobility and well-off enough that he could afford to be a NEET mooching off his family at the outbreak of the Revolution, etc. Louis XVI's own cousin
Louis-Philippe of Orleans threw in with the Revolution and was among those who voted to execute the king; it's probable that he wanted to hijack the Revolution and use it to usurp the throne, as he was an advocate of a constitutional monarchy (likely with himself as the monarch), but he obviously lost control of things and got executed by the mob he had helped to unleash.
Maybe it's less a question of wealth and more-so a question of spirit, in which case the American revolutionary spirit clearly was far superior to the French one in both character & consequence. The American elite (both the classical landowning aristocracy of the South & the mercantile bourgeoisie of New England) seem to have had a lot more practical real-world experience compared to the French one, ex. Washington grew up in the relatively humble Ferry Farm rather than any continental palace and actually fought as a soldier in the French & Indian Wars whereas niggers like Robespierre & the Duke d'Orleans never got their hands dirty or seriously risked their lives pre-Revolution, and that experience seems to have generally shaped the former into better men.
