I think complexity slowly developed over time to address certain needs of the time. Partly because software has been needing to do more. People and institution have become completely dependent on ease-of-use. When that happens software needs to be coded to be dummy proof and to have a large feature set. The second part is time. Programmers have need to find ways to decrease the amount of time programming takes to have free time to do other stuff, that causes programmers to rely on frameworks that are already established and creates a new market for coders to want to save time. Frameworks need to be complex to address a myriad of needs.
