One of the most common problems of human beings is that they frequently are mistaken in the differentiation of true values and those wrong ones dictated them by society. The main idea of “The Great Gatsby” by F. Scott Fitzgerald is to show that material and moral values can’t be mixed and love cannot be bought.
The post-war American society determined young and poor man Gatsby to think that material values are the main ones. After coming back from the First World War he dreamed of reunion with his beloved Daisy, but it turned out that Daisy didn’t need a poor guy – she had married the rich one. Such a situation influenced Gatsby, and he made the biggest essential mistake: he decided that money could make him happy and that he could get his love this way. So Gatsby quickly became extremely rich through some financial manipulations. But the point is that despite his attempt to get Daisy and her love back by demonstrating his wealth, he faces the mistake he didn’t recognize a long time ago: if Daisy had loved him, she wouldn’t have ever married another man. Evidently, that short reunion they had was just nothing for Daisy, because she abandoned Gatsby so easily when the first problem appeared.
The truth is very simple, and I think Fitzgerald reveals it by showing in the final part that Daisy was the kind of person embodying the moral vices of the American upper-class society of those times: frivolous, materialistic-based, and mercantile. When Gatsby was described as a man tangled in his wrong values. Fighting for some vague obsession of him, he eventually realized that nothing of what he was fighting for was worth it.
