I got it all from Johnny Tremayne.
The Crusaders fought for religious reasons, and they believed them sincerely, but if you believe money and real estate weren't involved then you haven't read any history at all.
TB, the American Revolution was a Bourgeois Revolution. The American ruling class were protecting their interests from the British ruling class.
Their political philosophy was sincerely believed, but so was the other side's. Remember, a third of the colonists supported Britain, and a third were neutral. And the war didn't start until the Brits started getting greedy by imposing tariffs and taxes to finance their own foreign wars. It wasn't all noble patriots against vicious tyrants. It was business.
