All the important foundational liberal economic theory was written before or during Marx's lifetime and Marx tore it to shreds. He dedicates tens of thousands of words and dozens of citations to discussing Adam Smith alone, and he actually kinda likes Adam Smith. All liberal economics since Marx has been lame attempts at repudiating or obfuscating the existence of surplus value, or class in general.
