Through a readjustment of economic conditions that would allow those who are poor or belonging to the middle class to have their fair share of goods, fulfillment and meaning could be achieved. Marx is interested in economic conditions by examining the meaning of life and believes that the meaning of life can only be analyzed in materialist terms. Therefore, Marx argues that people are defined by what they do or do. In a capitalist system, people are ultimately unhappy because they are unable to do what will satisfy them. Marx claims that if capitalism were overthrown, it would bring greater human happiness. In Marx's famous quote, "work is the source of happiness", he presents the importance of material life. Marx's view of happiness shows that it is the combination of creation and enjoyment. These philosophers offer a holistic perspective on achieving happiness. Looking at these philosophers, I think Marx is too focused on materialistic elements and that it is possible to be happy without having anything. It is also possible to be rich and unhappy. On the other hand, with the philosopher Kant, I do not believe that reason is the only determining factor in achieving happiness. My views seem to align most closely with those of St. Thomas and Plato. I agree that others can have different types of happiness depending on what they value, like Plato
