Kantian socialists at the turn of the twentieth century, as well as contemporary authors seeking a principle with which to condemn capitalism, have turned to Kant’s Formula of the End in Itself.

There are various strategies with which a Kantian might use FEI to condemn conduct that Kant did not use FEI to condemn. The article asks whether (...) any of the existing arguments from FEI employ plausible versions of these strategies to derive a strict duty from that formula’s Never Merely as a Means principle that condemns capitalism.
