I went to San Diego, the birthplace of the summer.

Marx’s central criticism of capitalism is not the injustice in the distribution of wealth; it is the perversion of labor into forced, alienated, meaningless labor, hence the transformation of man into a “crippled monstrosity.” Marx’s concept of labor as an expression of man’s individuality is succinctly expressed in his vision of the complete abolition of the lifelong submersion of a man in one occupation. Since the aim of human development is that of the development of the total, universal man, man must be emancipated from the crippling influence of specialization. In all previous societies, Marx writes, man has been “a hunter, a fisherman, a shepherd, or a critical critic, and must remain so if he does not want to lose his means of livelihood; while in communist society, where nobody has one exclusive sphere of activity but each can become accomplished in any branch he wishes, society regulates the general production and thus makes it possible for me to do one thing today and another tomorrow, to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticize after dinner, just as I have a mind, without ever becoming hunter, fisherman, shepherd or critic.”

Using the chain rule is like peeling an onion: you have to deal with each layer at a time, and if it is too big you will start crying.
