People should read Value Price and Profit because Marx proved that inflation is just companies raising prices, thoroughly debunks all the lies about causes of inflation that economists have been using to protect profits since before even his time.
All solid suggestions.
Wrt critique of the Gotha programme, it’s interesting to me that Marx was such a critic of Lassalle, so much so that Engels actually apologized for Marx’s harsh criticisms of the social democrat. Marx had called Lassalle a would be petty dictator or something like that. Except he was right, Lassalle was secretly plotting with von Bismarck on a plan to unify Germany under a bourgeois led social democracy, which von Bismarck could later seize absolute control over. Marx didn’t know about this conspiracy, he just reasoned it out.
Yeah I read WL&C after a failed attempt at reading Capital (I had never read much Marx other than the manifesto at that point) and realized I needed to understand his economics first, as I felt completely out of my depth. Turns out reading Capital v1, the first few chapters are just like that! But I’m glad I read WL&C, like you said its short and gave me something to chew on for a year or so before diving back into the big book.
I edited my comment above about CotGP. All solid recommendations, for exactly the reasons you state.
