Yeah, I think Adam Smith's invisible hand was playing with his own noodly appendage (I mean his mind, of course). About then the scientists kept coming up with new theories for new fields of study, physics, biology, evolution, geology, chemistry, and the economists wanted to play, too. This has persisted to this day; there are countless 'theories' in economics that proport to explain and predict, but none are really viable because by definition they are not objective. All are subject to manipulation, and the entire framework is artificial to begin with. It's a poorly designed socialogical study in greed, engineered in reverse.
