In economics, because everybody seemed to find it necessary to attack and condemn Karl Marx in their writings, I sought out his book, and although he kept me with a headache, I took him my authority. I was not prepared to understand him, but I was able to see in him a thoroughgoing critique of and condemnation of capitalism. It was like taking medicine for me to find that, indeed, American capitalism deserved all th hatred and contempt that I felt for it in my heart.
