Frameworks were invented to lower the barriers of entry to programming Bullshit. Modern frameworks like Django and Rails were extracted from real-life projects written from scratch by real programmers to let the real programmers re-use common web-development code and make it faster and more stable with time. When you use the framework you still can dive in pure Python/Ruby or even custom C/assembly extensions to optimize your bottlenecks if you really need.
