Marx permeates economics like Newton permeates physics.

If this seems like an absurd comparison, I would suggest reading both Philosophiæ Naturalis Principia Mathematica and Das Kapital.

Marx builds on Adam Smith and Ricardo among others and contributes an understanding of where money comes from and where profits come from among other things.
