It comes down to the power of incentives. As a developer, there is no incentive to make code simple. It's subconscious. Coming up with near-optimal solutions that are more maintainable in the long run takes time and effort. Most developers will happily sacrifice long-term maintainability to deliver fast short term results... Anyway, if the developer churns out code at an impressive rate for a few months, they'll probably be promoted to management and someone else will have to take over the mess they created.
